# Compiler Error CS0213

You cannot use the fixed statement to take the address of an already fixed expression

A local variable in an unsafe method or a parameter is already fixed (on the stack), so you cannot take the address of either of these two variables in a fixed expression. For more information, see Unsafe Code and Pointers.

## Example

The following sample generates CS0213.

// CS0213.cs
// compile with: /unsafe
public class MyClass
{
unsafe public static void Main()
{
int i = 45;
fixed (int *j = &i) { }  // CS0213
// try the following line instead
// int* j = &i;

int[] a = new int[] {1,2,3};
fixed (int *b = a)
{
fixed (int *c = b) { }  // CS0213
// try the following line instead
// int *c = b;
}
}
}
