split string after comma and till string ends- asp.net c#

I have a string of type

开发者_如何学C

ishan,training

I want to split the string after "," i.e i want the output as

training

NOTE: "," does not have a fixed index as the string value before "," is different at different times.

e.g ishant,marcela OR ishu,ponda OR amnarayan,mapusa etc...

From all the above strings i just need the part after ","

You can use String.Split:

string[] tokens = str.Split(',');
string last = tokens[tokens.Length - 1]

Or, a little simpler:

string last = str.Substring(str.LastIndexOf(',') + 1);

var arr = string.Split(",");
var result = arr[arr.length-1];

sourcestring.Substring(sourcestring.IndexOf(',')). You might want to check sourcestring.IndexOf(',') for -1 for strings without ,.

I know this question has already been answered, but you can use linq:

string str = "1,2,3,4,5";
str.Split(',').LastOrDefault();

Although there are several comments mentioning the issue of multiple commas being found, there doesn't seem to be any mention of the solution for that:

string input = "1,2,3,4,5";
if (input.IndexOf(',') > 0)
{
    string afterFirstComma = input.Split(new char[] { ',' }, 2)[1];
}

This will make afterFirstComma equal to "2,3,4,5"

Use String.Split(",") assign the result in to a string array and use what you want.

Heres a VB version. I'm sure its easy to translate to C# though

 Dim str as string = "ishan,training"
 str = str.split(",")(1)

 return str
