Cannot take the address of the given expression C# pointer

Question

Consider the following code in an unsafe context:

string mySentence = \"Pointers in C#\";

fixed (char* start = mySentence) // this is the line we\'re talkin         


        

Answer 1

This doesn't work because you're trying to access a string. If you change your code to:

char[] mySentence = "Pointers in C#".ToCharArray();

fixed (char* start = &mySentence[0])
{
    char* p = start;

    do
    {
        Console.Write(*p);
    }
    while (*(++p) != '\0');
}

Console.ReadLine();

everything will work fine.
