what is trim in c#

Trim eliminates leading and trailing whitespace. We need to remove whitespace from the beginning or ending of a string. We use the .NET Framework's Trim method to do this efficiently. This method removes any characters specified.

 

Trim Example input & output

1)      String input:       "   This is an example string. "

      Trim method Output: "This is an example string."

2)       String input:       "This is an example string.\r\n\r\n"

      Trim method Output: "This is an example string."

3)       String input:       "\t, again and again."

      Trim method Output:   "again and again."

Note:  You can remove commas, spaces, and tabs.

Example

This first example removes space characters from the beginning and end of a C# string. Note that when you call Trim on a string, it copies the string and returns a modified version of that copy. The original is not changed.

 Example Program for trim in C#

using System;

class Program

{

    static void Main()

    {

             // Input string

             string st = "  This is an example string. ";

             // Call Trim instance method.

             // This returns a new string copy.

             st = st.Trim();

             Console.WriteLine(st);

    }

}

Output:-(Spaces were removed.)

This is an example string.
