C# Error CS1733 – Expected expression

C# Error

CS1733 – Expected expression

Reason for the Error & Solution

Expected expression.

This error is produced whenever the compiler is expecting an expression on the line where the error occurred. In the following example, the trailing comma in the initializer indicates to the compiler that another expression will follow.

To correct this error

  • Provide the missing expression.

  • Remove the tokens that are causing the compiler to expect an expression.


The following example produces CS1733 because of the trailing comma:

// cs1733.cs  
using System.Collections.Generic;  
public class Test  
    public static void Main()  
        List<int> list = new List<int>() {{ 1, 2, }};// CS1733
