Compiler Error CS1949

The contextual keyword 'var' cannot be used in a range variable declaration.

A range variable is implicitly typed by the compiler. There is no need to use var with a range variable.

To correct this error

1. Remove the var keyword from in front of the range variable.

Example

The following example generates CS1949:

// cs1949.cs  
using System;  
using System.Linq;  
class Test  
{  
    static void Main()  
    {  
        var x = from var i in Enumerable.Range(1, 100) // CS1949  
        select i;  
    }  
}
