How do I write at a specific index of a line?

Good day Stackoverflow,
I want to write some text at a specific point of a line in a txt-file.
So I want to write something between two ; in the line.
The Line of the textfile is: 20180912_0149;KIV\vischer;12.09.2018;01:49;; .
I want to write it if I click the "Geht" Button. I tried different things with streamreader and writer but I don't get to a solution.
Here is my code of the aspx.cs and my helper class:
Aspx.cs:
namespace Zieterfassung_0._0._2pre_alpha
{
public partial class Zeiten : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string sPath = #"C:\VSTO\Projects\Zeiterfassung\Zeiterfassung\obj\Debug\Zeiten.txt";
tb_User.Text = WindowsIdentity.GetCurrent().Name.ToString();
tb_Datum.Text = DateTime.Now.ToString("dd.MM.yyyy");
tb_Zeit.Text = DateTime.Now.ToString("hh:mm");
cZeile KommtDatumZeit = new cZeile();
if (File.Exists(sPath))
{
using (StreamReader sr = new StreamReader(sPath))
{
while (!sr.EndOfStream)
{
KommtDatumZeit = cZeiterfassung.GetZeileObjectFromZeileString(sr.ReadLine(), ";");
}
}
}
tb_Kommt.Text = KommtDatumZeit.dtKommt.ToString();
}
protected void btn_Geht_Click(object sender, EventArgs e)
{
string sAusgabeGeht = string.Format("{0:hh:mm}", tb_Zeit.Text);
string sPath = #"C:\VSTO\Projects\Zeiterfassung\Zeiterfassung\obj\Debug\Zeiten.txt";
FileInfo fi = new FileInfo(sPath);
cZeile Geht = new cZeile();
using (StreamReader sr = new StreamReader(sPath))
{
Geht = cZeiterfassung.GetZeileObjectFromZeileString(sr.ReadLine(), ";");
}
using(StreamWriter sw = new StreamWriter(sPath))
{
}
}
}
}
Helperclass for splitting and array:
namespace Prog
{
public static class cZeiterfassung
{
public static cZeile GetZeileObjectFromZeileString(string Zeile, string Trenner)
{
cZeile ZeileReturn = new cZeile();
string[] separators = { Trenner };
string[] arZeile = Zeile.Split(separators, StringSplitOptions.None);
ZeileReturn.ID = arZeile[0];
if (arZeile[1].IndexOf("\\") != -1)
{
ZeileReturn.Domain = arZeile[1].Substring(0, arZeile[1].IndexOf("\\"));
if (arZeile[1].Length >= arZeile[1].IndexOf("\\"))
ZeileReturn.User = arZeile[1].Substring(arZeile[1].IndexOf("\\") + 1);
}
else
ZeileReturn.User = arZeile[1];
ZeileReturn.Datum = arZeile[2];
ZeileReturn.Kommt = arZeile[3];
ZeileReturn.Geht = arZeile[4];
if(!string.IsNullOrEmpty(arZeile[2]))
ZeileReturn.dtDatum = Convert.ToDateTime(arZeile[2]);
if(!string.IsNullOrEmpty(arZeile[3]))
ZeileReturn.dtKommt = Convert.ToDateTime(arZeile[3]);
if (!string.IsNullOrEmpty(arZeile[4]))
ZeileReturn.dtGeht = Convert.ToDateTime(arZeile[4]);
return ZeileReturn;
}
}//cZeiterfassung
public class cZeile
{
public string ID { get; set; }
public string Domain { get; set; }
public string User { get; set; }
public string Datum { get; set; }
public string Kommt { get; set; }
public string Geht { get; set; }
public DateTime dtDatum { get; set; }
public DateTime dtKommt { get; set; }
public DateTime dtGeht { get; set; }
public string Dauer { get; set; }
}
}

I can't quite Point out what are you trying to do from your code, but from the question you asked:
I would look into every line if you are looking for a specific line
string Data = "";
using(StreamReader Sr = new StreamReader(Path))
{
while(!Sr.EndOfStream())
{
string UseMe = Sr.ReadLine();
Data += UseMe;
}
}
Now you could just validate each line. With the Data-string I gave you a possibility to build each line into one string
I hope I could help you, otherwise contact me directly (I also speak german I guess this is easier for you)

If your file isn't big, I propose you to write to new files with new data.
This is the idea
string[] lines = File.ReadAllLines(sPath);
for (int i = 0; i < lines.Length; i++)
{
if (lines[i].IndexOf(";;") != -1)
{
lines[i] = lines[i].Insert(line.IndexOf(";;"), "xxx");
}
}
File.WriteAllLines(sPathTemp, lines);

Merging C# code in Xamarin Android

Please help me to solve this, or at least help me to further research the problem.
Thank you.

You have put an infinite loop in your code. Please remove it.
For example:
private void ButtonClick2(object sender, EventArgs e)
{
var api = new GingerItApi();
Console.Write("Text to check: ");
var text = Label.Text;
if (!string.IsNullOrEmpty(text))
{
try
{
var result = api.Check(text);
if (result?.Corrections?.Count != 0)
{
for (int i = 0; i < result.Corrections.Count; i++)
{
var item = result.Corrections[i];
var mistakes = string.Join(", ", item.Mistakes.Select(x => $"\"{text.Substring(x.From, x.To - x.From + 1)}\""));
var suggestions = string.Join(", ", item.Suggestions.Select(x => $"\"{x.Text}\""));
Label1.Text = $" {i + 1}: {mistakes} >> {suggestions}";
}
}
else
{
Label1.Text = "Looks okay.\n";
Console.WriteLine("Looks okay.\n");
}
}
catch (Exception ex)
{
Console.WriteLine($"**Error: {ex.Message}\n");
}
}
}
And the result is:

JSON format writing to file

I want to write my items by JSON format, but My files empty. Here is my two class:
public class DocPart
{
public string Title { get; set; }
public bool Checked { get; set; }
}
public class DocConfig
{
public List<DocPart> Parts { get; set; }
public static DocConfig LoadFromString(string jsonData)
{
var config = new DocConfig();
config.Parts = new List<DocPart>();
var part = new DocPart
{
Title = "chapter1",
"chapter2",
Checked = checkBox1.Checked,
checkbox2.Checked
};
config.Parts.Add(part);
var configString = config.SaveToString();
File.WriteAllText(#"C:\link to my file", configString);
var configString = File.ReadAllText(#"C:\link to my file");
var config = DocConfig.LoadFromString(configString);
foreach (var part in config.Parts)
{
if (part.Title == "chapter1")
chekbox1.Checked = part.Checked;
if (part.Title == "chapter2")
checkbox2.Checked = part.Checked;
var serializer = new DataContractJsonSerializer(typeof(DocConfig));
var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonData));
var config = (DocConfig)serializer.ReadObject(ms);
return config;
}
}
public string SaveToString()
{
var serializer = new DataContractJsonSerializer(typeof(DocConfig));
var ms = new MemoryStream();
serializer.WriteObject(ms, this);
return Encoding.UTF8.GetString(ms.ToArray());
}
}
So I run my program, everything looks okey, but my file is still empty without any JSON format data. Maybe you could help me?
Thanks.

{
public string Title { get; set; }
public bool Checked { get; set; }

{

var part1 = new DocPart
{
Title = "chapter1",
Checked = checkBox1.Checked
};
config.Parts.Add(part1);
var part2 = new DocPart
{
Title = "chapter2",
Checked = checkBox2.Checked
};
config.Parts.Add(part2);
var configString = config.SaveToString();
File.WriteAllText(#"d:\temp\test.json", configString);
configString = File.ReadAllText(#"d:\temp\test.json");
var ms = new MemoryStream(Encoding.UTF8.GetBytes(configString));
var serializer = new DataContractJsonSerializer(typeof(DocConfig));
config = (DocConfig)serializer.ReadObject(ms);
foreach (var part in config.Parts)
{
if (part.Title == "chapter1")
{

Debug.WriteLine("chapter1" + part.Checked);
}
if (part.Title == "chapter2")
{

Debug.WriteLine("chapter2" + part.Checked);
}
}
return config;
}
public string SaveToString()
{
var serializer = new DataContractJsonSerializer(typeof(DocConfig));
var ms = new MemoryStream();
serializer.WriteObject(ms, this);
return Encoding.UTF8.GetString(ms.ToArray());
}
}

// Now we have our Json Object...
SampleJson sample = JsonConvert.DeserializeObject<SampleJson>(testJson);
// We convert it back into a string with indentation...
string jsonString = JsonConvert.SerializeObject(sample, Newtonsoft.Json.Formatting.Indented);
// Now simply save to file...
using (StreamWriter writer = new StreamWriter(filePath))
{
writer.WriteLine(jsonString);
}
Process.Start(filePath);
}
// The following classes are what the `testJson` string is deserialized into.

{
[JsonProperty("para")]
public string Para { get; set; }
[JsonProperty("GlossSeeAlso")]

match value in one list with another and write value to other list

I have one list that is written to this class:
public class keyfrs
{
public keyfrs() { }
public long regID { get; set; }
public long ID { get; set; }
public string county { get; set; }
public string state { get; set; }
}
List<keyfrs> k = {1,2,3,4}] regID
{A,B,C,D} ID
I have another list class like this:
public class states
{
public states() { }
public long regID { get; set; }
public string state { get; set; }
public string county { get; set; }
}
List<states> s = {1,2,3,4}regID
{MA,NY,CT}state
{Suffolk,NY,Hampden}county
Want to write the county and state to the keyfrs list that matches with the regID from the lists.
What my program does so far is parse in two files and write each one to the different class list it corresponds to. As you can see both classes have a regID column. What I need to do is match the two lists together on regID and write the county and state to the keyfrs list class to then output that list to a new file with these added column in it.
static void Main(string[] args)
{
PARSEkeYfrs();
parsestateFile();
matchValues();
outputFile();
}
private static void outputFile()
{
string filename = #"c:\keyswCounty.csv";
using(StreamWriter write = new StreamWriter(filename))
{
write.WriteLine("RegIF"+","+"ID"+","+"County"+","+"State");
foreach(keyfrs k in keysandID)
{
write.WriteLine(k.regID +"," +k.ID+","+k.county+","+k.state);
}
}
}
private static void matchValues()
{
foreach(keyfrs k in keysandID)
{
}
}
private static void parsestateFile()
{
int a = 0;
string filename = #"c:\ALLStates.txt";
using (StreamReader read = new StreamReader(filename))
{
read.ReadLine();
while (!read.EndOfStream)
{
a++;
try{
string line = read.ReadLine();
string[] splitline = line.Split(',');
if(splitline[1]!="")
{
states s = new states();
s.regID = Convert.ToInt64(splitline[0]);
s.county = Convert.ToString(splitline[1]);
s.state = Convert.ToString(splitline[2]);
stateFile.Add(s);
}
}
catch(Exception ex)
{
string.Format("error:{0}" + ex.Message.ToString());
}
}
}
}
private static void PARSEkeYfrs()
{ int a = 0;

{
try{
a++;
string line = read.ReadLine();
string[] splitline = line.Split(',');
if(splitline[1]!="")
{
keyfrs k = new keyfrs();
k.regID = Convert.ToInt64(splitline[0]);
k.ID = Convert.ToInt64(splitline[1]);
k.county = "";
k.state = "";
keysandID.Add(k);
}
}
catch(Exception ex)
{
string.Format("error:{0}"+ex.Message.ToString());
}
}
}
}

switched the state list to a dictionary and matched the values by the key value pair by using the TryGetValue method.
