What are pointer data types in C#?
A pointer is a variable whose value is the address of another variable i.e., the direct address of the memory location. Similar to any variable or constant, you must declare a pointer before you can use it to store any variable address.
The syntax of a pointer is −
type *var-name;
The following is how you can declare a pointer type −
int *ip; /* pointer to an integer */ double *dp; /* 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.
Here is the module showing how to declare and use a pointer variable. We have used unsafe modifier here −
static unsafe void Main(string[] args) {
int var = 20;
int* p = &var;
Console.WriteLine("Data is: {0} ", var);
Console.WriteLine("Address is: {0}", (int)p);
Console.ReadKey();
}
