split string before hyphen - asp.net c#

Question

I have a string :

10989898 - test1

or another example:

123178239182 - test2

I need the output like this:

In first case:

10989898 

In second case:

123178239182

means the value before hyphen. How can I do that?

Solution 1

string result = theString.Substring(0, theString.IndexOf("-")).Trim();

Solution 2

You can use the String Split method:

string[] splitString = string.split('-');

string requiredString = splitString[0];

Solution 3

string s = "10989898 - test1";
string str = s.Substring( 0, s.IndexOf( "-" ) ).Trim();

Needs a trim or the result will still have the space at the end

+1 for remembering to Trim(). Just because you can't see that space doesn't mean it's not there.

This is bad, your creating a throwaway array for no reason
