What are pointers in C#?
Pointer is a variable whose value is the address of another variable i.e., the direct address of the memory location.
The syntax of a pointer is −
type *var-name;
The following is how you can declare a pointer type −
double *z; /* pointer to a double */
C# allows using pointer variables in a function of code block when it is marked by the unsafe modifier. The unsafe code or the unmanaged code is a code block that uses a pointer variable.
The following is our module showing how to declare and use a pointer variable. We have used unsafe modifier here −
static unsafe void Main(string[] args) {
int val = 50;
int* x = &val;
Console.WriteLine("Data: {0} ", val);
Console.WriteLine("Address: {0}", (int)x);
Console.ReadKey();
}
