Compile Unsafe Code in C#

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

For example, to compile a program named one.cs containing unsafe code, from command line, give the command −

csc /unsafe one.cs

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.
• Select the option "Allow unsafe code".
