How to remove double quotes from string using C#?

Here are few ways to remove double quotes from string using C#

var yourString= "-10,20";
yourString = yourString.Replace('"', ' ').Trim();

OR

Using .Trim

yourString= yourString.Trim('"');

OR

yourString=yourString.Replace("\"", "");

Any of the above solutions should work.

You can simply use Replace method in C#

yourString = yourString.Replace("\"", string.Empty).Trim();

We have added "\" (backslash) before double quotes to escape the quotation mark.

Simply try Trim() in C#

using System;
					
public class Program
{
	public static void Main()
	{
		var str = "\"Add doublequotes\"";
		Console.WriteLine(str);

		//remove double quotes
		Console.WriteLine(str.Trim('"'));
	}
}

Output:

"Add doublequotes"
