Compiler Error CS1665

  • Article

Fixed size buffers must have a length greater than zero

This error occurs if a fixed size buffer is declared with a zero or negative size. The length of a fixed size buffer must be a positive integer.

Example

The following sample generates CS1665.

// CS1665.cs
// compile with: /unsafe /target:library
struct S
{ 
   public unsafe fixed int A[0];   // CS1665
}
