C# Compiler Error

CS0145 – A const field requires a value to be provided

Reason for the Error

When declaring a constant, you will have to initialize the constant variable with the value. When you don’t initialize the constant variable, you’ll receive this error.

For example, the below C# code snippet will result with the C# compiler error CS0145 as the constant field Id is not initialized.

RUN CODE SNIPPET
namespace DeveloperPublishNamespace
{
    public class DeveloperPublish
    {
        const int Id;
        public static void Main()
        {
           
        }
    }

}

Solution

When declaring the constant variable, ensure that you initialize it. Alternatively, you can look at using readonly instead of const where you don’t want to initialize the variable.
