How to remove the first character of a string in C#
In this tutorial, we are going to learn about how to remove the first character of a string in C#.
Consider, we have the following string.
string str = "king";
Now, we want to remove the first character k
from the above string.
Removing the first character
To remove the first character of a string, we can use the String.Remove()
method by passing the 0,1
as arguments.
Note: In C# strings are the sequence of characters that can be accessed by using its character index, where the first character index is 0 and the last character index is string.Length-1.
Here is an example, that removes the first character k
from the following string:
using System;
class RemoveCharacter {
static void Main() {
string s = "king";
string result = s.Remove(0,1);
Console.WriteLine(result);
}
}
Output:
"ing"
In the above code, 0
is the start index and 1
is the number of characters we need to remove from the start index.
Similarly, we can also use the String.Substring()
method in C#.
using System;
class RemoveCharacter {
static void Main() {
string s = "king";
string result = s.Substring(1);
Console.WriteLine(result);
}
}
Note: The String.Remove(), Substring() methods return a new string with the specified characters instead of modifying the original string.
