Trimming degree symbol on C#

Question

Can anyone tell me why this is not working:

string txt = "+0°1,0'";
string degree = txt.TrimEnd('°');

I am trying to separate the degrees on this string, but after this, what remains on degree is the same content of txt.

I am using C# in Visual Studio.

Answer 1

string.TrimEnd remove char at the end. In your example, '°' isn't at the end.

For example :

string txt = "+0°°°°";
string degree = txt.TrimEnd('°');
// degree => "+0"

If you want remove '°' and all next characters, you can :

string txt = "+0°1,0'";
string degree = txt.Remove(txt.IndexOf('°'));
// degree => "+0"

Answer 2

string txt = "+0°1,0'";
if(txt.IndexOf('°') > 0) // Checking if character '°' exist in the string
{
   string withoutdegree = txt.Remove(txt.IndexOf('°'),1);
}

Answer 3

Another safe way of handling the same is using the String.Split method. You will not have to bother to verify the presence of the character in this case.

string txt = "+0°1,0'";
var str = txt.Split('°')[0]; // "+0"

string txt = "+01,0'";
var str = txt.Split('°')[0]; // "+01,0'"

You can use this to remove all the '°' symbols present in your string using String.Replace

string txt = "+0°1,0'°°";
var text = txt.Replace(@"°", ""); // +01,0'

Edit: Added a safe way to handle the OP's exact query.
