Compiler Error CS0650

Bad array declarator: To declare a managed array the rank specifier precedes the variable's identifier. To declare a fixed size buffer field, use the fixed keyword before the field type.

An array was declared incorrectly. In C#, unlike in C and C++, the square brackets follow the type, not the variable name. Also, realize that the syntax for a fixed size buffer differs from that of an array.

Example

The following example code generates CS0650.

// CS0650.cs
public class MyClass
{
   public static void Main()
   {
// Generates CS0650. Incorrect array declaration syntax:
      int myarray[2];   
 
      // Correct declaration.
      int[] myarray2;

      // Declaration and initialization in one statement
      int[] myArray3= new int[2] {1,2}
      
      // Access an array element.
      myarray3[0] = 0;
    }
}

The following example shows how to use the fixed keyword when you create a fixed size buffer:

// This code must appear in an unsafe block. 
public struct MyArray 
{
    public fixed char pathName[128];
}
