C# Error CS1041 – Identifier expected; ‘{1}’ is a keyword

C# Error

CS1041 – Identifier expected; ‘{1}’ is a keyword

Reason for the Error & Solution

Identifier expected, ‘keyword’ is a keyword

A reserved word for the C# language was found where an identifier was expected. Replace the with a user-specified identifier.

Example 1

The following sample generates CS1041:

// CS1041a.cs  
class MyClass  
{  
    public void f(int long)   // CS1041  
    // Try the following instead:  
    // public void f(int i)  
    {  
    }  
  
    public static void Main()  
    {  
    }  
}  

Example 2

When you are importing from another programming language that does not have the same set of reserved words, you can modify the reserved identifier with the @ prefix, as demonstrated in the following sample.

An identifier with an @ prefix is called a verbatim identifier.

// CS1041b.cs  
class MyClass  
{  
    public void f(int long)   // CS1041  
    // Try the following instead:  
    // public void f(int @long)  
    {  
    }  
  
    public static void Main()  
    {  
    }  
}
