The string i

Answer 1

var code = myString.Split(new [] {"code"}, StringSplitOptions.None)[1];
// code = " : -1"

You can tweak the string to split by - if you use "code : ", the second member of the returned array ([1]) will contain "-1", using your example.

Answer 2

string toBeSearched = "code : ";
string code = myString.Substring(myString.IndexOf(toBeSearched) + toBeSearched.Length);

Something like this?

Perhaps you should handle the case of missing code :...

string toBeSearched = "code : ";
int ix = myString.IndexOf(toBeSearched);

if (ix != -1) 
{
    string code = myString.Substring(ix + toBeSearched.Length);
    // do something here
}

Answer 3

use indexOf() function

string s = "Error description, code : -1";
int index = s.indexOf("code");
if(index != -1)
{
  //DO YOUR LOGIC
  string errorCode = s.Substring(index+4);
}

Answer 4

Simpler way (if your only keyword is "code" ) may be:

string ErrorCode = yourString.Split(new string[]{"code"}, StringSplitOptions.None).Last();

Answer 5

string originalSting = "This is my string";
string texttobesearched = "my";
string dataAfterTextTobeSearch= finalCommand.Split(new string[] { texttobesearched     }, StringSplitOptions.None).Last();
if(dataAfterTextobeSearch!=originalSting)
{
    //your action here if data is found
}
else
{
    //action if the data being searched was not found
}

Answer 6

add this code to your project

  public static class Extension {
        public static string TextAfter(this string value ,string search) {
            return  value.Substring(value.IndexOf(search) + search.Length);
        }
  }

then use

"code : string text ".TextAfter(":")
