I have the code below when I replace variable text0 with text1. I got an error String cannot be of zero length. Parameter name: oldValue.
string text0 = string.Empty;
string text1 = "This is text 1";
string text2 = text1.Replace(text0, "");
Console.WriteLine(text2); I don't know what is oldValue param? and How can I fix this issue?

In c#/ Asp.net Core,
Replace()method accepts two parameters as below:public String Replace(String oldValue, String? newValue);In that,
oldValueparameter is required and not accept value null or empty. In your exampletext0variable is empty so it throws that exception. Please sure thattext0must NOT null or empty.
