What is unmanaged code in C#?
The following states what is an unmanaged code −
- Applications that are not under the control of the CLR are unmanaged
- The unsafe code or the unmanaged code is a code block that uses a pointer variable.
- The unsafe modifier allows pointer usage in unmanaged code.
Here is the module showing how to declare and use a pointer variable. We have used the unsafe modifier here.

Example
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();
}
