How to compile unsafe code in C#?

For compiling unsafe code, you have to specify the /unsafe command-line switch with command-line compiler.

Under Visual Studio IDE, enable use of unsafe code in the project properties. The following are the steps −

• Open Project properties by double clicking the properties node in the Solution Explorer.
• Click on the “Build” tab.
