C# string replace
(9 answers)
Closed 3 years ago.
I want to dynamically replace an exact sub string from a string. For ex I want to replace "dis.[Test Table]" to "dbo.[Test Table]" in the following string:
SELECT Name FROM dis.[Test Table].
Note that I it could be any text and any sub string. It will replace only exactly matched sub string as many times as it will occur.
use String.Replace() Method
fullString = fullString.Replace("oldSubString", "newSubString");
Just to elaborate further, your example can be written as:
var newString = "SELECT Name FROM dis.[Test Table]".Replace("dis.[Test Table]","dbo.[Test Table]");
// newString will become "SELECT Name FROM dbo.[Test Table]"

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

How can I check if a string exists in another string
(10 answers)
Closed 5 years ago.
I'm working on a Existing Class file(.cs) which fetches a string with some data in it.
I need to check if the string contains a word. String has no blank spaces in it.
The string-
"<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>"
I need to check if the string contains 'ReleaseUserAuthPending' in it.
You can try this:
var strValue = "<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>";
if (strValue.Contains("ReleaseUserAuthPending"))
{
//Do stuff
}
Refer About String - Contains function
For your information: Contains function is case-sensitive. If you want to make this Contains function as case-insensitive. Do the following step from this link.
bool containsString = mystring.Contains("ReleaseUserAuthPending");
Try
String yourString = "<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>";
if(yourString.Contains("ReleaseUserAuthPending")){
//contains ReleaseUserAuthPending
}else{
//does not contain ReleaseUserAuthPending
}

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.

How to remove a string from a string
(4 answers)
Closed 8 years ago.
I've this kind of string.
FullName:ae876ggfg777878848adgf877
And I want to remove "FullName:", so the output as follows:
ae876ggfg777878848adgf877
How can I do that?
I tried this:
var index = myText.IndexOf(":");
var result = myText.Remove(index);
But the output is like this:
FullName
Which I do not expect.
IndexOf returns the index of whatever string/character you give it, so in your case, the index of :.
Remove, according to the documentation:
Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted.
So what's happening here is you're removing everything after and including the :
You should be using String.Replace:
string removed = myText.Replace("FullName:", "");
Use String.Substring() and get the start index by using String.IndexOf('character') + 1.
string s = "FullName:ae876ggfg777878848adgf877";
Console.WriteLine(s.Substring(s.IndexOf(':')+1));

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);
