Question

I want to get pointer of first entry in the array. This is how I tried

int[] Results = { 1, 2, 3, 4, 5 };

unsafe
{
    int* FirstResult = Results[0];
}

Get following compilation error. Any ideas how to fix it?

You can only take the address of an unfixed expression inside of a
fixed statement initializer

The error codes are magic to get the answer – search for error code (CS0212 in your case) and you get explanation with proposed fix in a lot of case.

Code from the page:

   unsafe public void mf()
   {
      // Null-terminated ASCII characters in an sbyte array 
      sbyte[] sbArr1 = new sbyte[] { 0x41, 0x42, 0x43, 0x00 };
      sbyte* pAsciiUpper = &sbArr1[0];   // CS0212
      // To resolve this error, delete the previous line and 
      // uncomment the following code:
      // fixed (sbyte* pAsciiUpper = sbArr1)
      // {
      //    String szAsciiUpper = new String(pAsciiUpper);
      // }
   }
