C# Compiler Error
CS0102 – The type ‘type name’ already contains a definition for ‘identifier’
Reason for the Error
You will receive this error when you declare multiple identifiers with the same name with-in the same scope (Eg : same class)
For example, the below code snippet contains the two string fields with-in the class Class1.
namespace DeveloperPublish { class Class1 { string Website1 = "DeveloperPublish"; string Website1 = "By Senthil Kumar"; } public class Program { public static void Main() { } } }
This will result with the error.
Error CS0102 The type ‘Class1’ already contains a definition for ‘Website1’ ConsoleApp2 C:\Users\admin\source\repos\ConsoleApp2\ConsoleApp2\Program.cs 6 Active
Solution
To fix the error, try renaming the duplicate identifier.
