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

Try this:
unsafe
{
fixed (int* FirstResult = &Results[0])
{
}
}
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);
// }
}
The error message is pretty clear. You can refer to MSDN.
unsafe static void MyInsaneCode()
{
int[] Results = { 1, 2, 3, 4, 5 };
fixed (int* first = &Results[0]) { /* something */ }
}
