How to remove a defined part of a string?

Question

I have this string: \"NT-DOM-NV\\MTA\" How can I delete the first part: \"NT-DOM-NV\\\" To have this as result: \"MTA\"

How is it possible with RegEx?

Answer 1

Try

string string1 = @"NT-DOM-NV\MTA";
string string2 = @"NT-DOM-NV\";

string result = string1.Replace( string2, "" );

Answer 2

Given that "\" always appear in the string

var s = @"NT-DOM-NV\MTA";
var r = s.Substring(s.IndexOf(@"\") + 1);
// r now contains "MTA"

Answer 3

If there is always only one backslash, use this:

string result = yourString.Split('\\').Skip(1).FirstOrDefault();

If there can be multiple and you only want to have the last part, use this:

string result = yourString.SubString(yourString.LastIndexOf('\\') + 1);

Answer 4

string.TrimStart(what_to_cut); // Will remove the what_to_cut from the string as long as the string starts with it.  

"asdasdfghj".TrimStart("asd" ); will result in "fghj".
"qwertyuiop".TrimStart("qwerty"); will result in "uiop".

---

public static System.String CutStart(this System.String s, System.String what)
{
    if (s.StartsWith(what))
        return s.Substring(what.Length);
    else
        return s;
}

"asdasdfghj".CutStart("asd" ); will now result in "asdfghj".
"qwertyuiop".CutStart("qwerty"); will still result in "uiop".

Answer 5

you can use this codes:

str = str.Substring (10); // to remove the first 10 characters.
str = str.Remove (0, 10); // to remove the first 10 characters
str = str.Replace ("NT-DOM-NV\\", ""); // to replace the specific text with blank

//  to delete anything before \

int i = str.IndexOf('\\');
if (i >= 0) str = str.SubString(i+1);

Answer 6

 string s = @"NT-DOM-NV\MTA";
 s = s.Substring(10,3);
