Why is \ character being doubled in my # string?
(3 answers)
Closed 8 years ago.
I have a small piece of code:
public static void Write(string filename){
string time = DateTime.Now.ToString("hh:mm tt");
int date = int.Parse(DateTime.Now.ToString("yyyyMMdd"));
string path = #"C:\Users\Public\" + filename;
}
If I debug and stop just after path is set it looks like “C:\\\Users\\\Public\\\filename.txt”.
Can anyone tell me why it has the double slashes? Is the '#' sign actually messing it up in this case?
How I may get it as “C:\Users\Public\filename.txt”
The double slashes are only there for the debugger, not your actual application. Your code is fine.

string.Replace (or other string modification) not working
(4 answers)
Closed 12 months ago.
I'm trying to replace a special character "½" with ".5"
cell.InnerText="o208½-105u208½-109o208-110u209-110";
string tempStr=cell.InnerText;
if (cell.InnerText.Contains("½"))
{
cell.InnerText.Replace("½", ".5");
}
string tempStr1 = cell.InnerText;
but my C# .Replace isn't working , I get the same result.
String is an immutable type. Compiler creates a new string after replacing. So try just this
var innerText = "o208½-105u208½-109o208-110u209-110";
innerText= innerText.Replace("½", ".5");
result
before - o208½-105u208½-109o208-110u209-110
after - o208.5-105u208.5-109o208-110u209-110

i want to know how to insert umlaut(") to StringBuilder..
TEXT in HTML :::
<iframe src ="navigation.html" linkTarget = "iframe">
C#
StringBuilder htmlBuilder = new StringBuilder();
htmlBuilder.AppendLine("<iframe src = 'navigation.html' linkTarget = 'iframe'>")
With 'navigation.html' html not working correctly ... i need Append "navigation.html" ,
I want to hear a lot of yours ideas how it could be made ...
Like using chars .. etc.. :)
I think you're just missing the option of using \ to escape the double quote within a string literal:
htmlBuilder.AppendLine("<iframe src=\"navigation.html\" linkTarget=\"iframe\">");

C# string replace does not actually replace the value in the string [duplicate]

I am attempting to replace characters in a string data type. Below is my code, but the ' is not being replaced with ''. Am I mis-understanding how the replace() function operates? What should I do in order to change the string to High Flying Picture''s?
This is the syntax I attempted.
public static void Test()
{
string strVar = "High Flying Picture's";
strVar.Replace("'", "''");
Console.WriteLine(strVar);
}
strVar = strVar.Replace("'", "''");
You need to reassign it.

Make first letter of a string upper case (with maximum performance)
(42 answers)
Closed 7 years ago.
I have already taken a look at such posts like:
Format to first letter uppercase
How to capitalise the first letter of every word in a string
But none of these seem to actually work. I would have thought to start with that there would just be a:
.Capitalize();
Like there is:
.Lower(); & .Upper();
Are there any documentation or references regarding converting to a string like the following?
string before = "INVOICE";
To then becoming:
string after = "Invoice";
I receive no errors using the way the posts solutions I read give me, however, the before still remains capitalized.
What about using ToUpper on the first char and ToLower on the remaining string?
string after = char.ToUpper(before.First()) + before.Substring(1).ToLower();
You can create a method that does something like this:
string UppercaseFirst(string str)
{
if (string.IsNullOrEmpty(str))
return string.Empty;
return char.ToUpper(str[0]) + str.Substring(1).ToLower();
}
And use it like this:
string str = "thISstringLOokSHorribLE";
string upstr = UppercaseFirst(str);
to get this:

How to get the last five characters of a string using Substring() in C#?
(12 answers)
Closed 9 years ago.
I have a string that could look like this: smithj_Website1 or it could look like this rodgersk_Website5 etc, etc. I want to be able to store in a string what is after the "_". So IE (Website1, Website5,..)
Thanks
Should be a simple as using substring
string mystr = "test_Website1"
string theend = mystr.SubString(mystr.IndexOf("_") + 1)
// theend = "Website1"
mystr.IndexOf("_") will get the position of the _ and adding one to it will get the index of the first character after it. Then don't pass in a second parameter and it will automatically take the substring starting at the character after the _ and stopping and the end of the string.
int startingIndex = inputstring.IndexOf("_") + 1;
string webSite = inputstring.Substring(startingIndex);
or, in one line:
string webSite = inputstring.Substring(inputstring.IndexOf("_") + 1);
