I have read this question to get first char of the string. Is there a way to get the first n number of characters from a string in C#?
I don't know why anybody mentioned this. But it's the shortest and simplest way to achieve this.
string str = yourString.Remove(n);
n - number of characters that you need
n
Example
var zz = "7814148471"; Console.WriteLine(zz.Remove(5)); //result - 78141
