Compiler Error CS1716

Do not use 'System.Runtime.CompilerServices.FixedBuffer' attribute. Use the 'fixed' field modifier instead.

This error arises in an unsafe code section that contains a fixed-size array declaration similar to a field declaration. Do not use this attribute. Instead, use the keyword fixed.

Example

The following example generates CS1716.

// CS1716.cs  
// compile with: /unsafe  
using System;  
using System.Runtime.CompilerServices;  

public struct UnsafeStruct  
{  
    [FixedBuffer(typeof(int), 4)]  // CS1716  
    unsafe public int aField;  
    // Use this single line instead of the above two lines.  
    // unsafe public fixed int aField[4];  
}  

public class TestUnsafe  
{  
    static int Main()  
    {  
        UnsafeStruct us = new UnsafeStruct();  
        unsafe  
        {  
            if (us.aField[0] == 0)  
                return us.aField[1];  
            else  
                return us.aField[2];  
        }  
    }  
}
