To use unsafe code blocks, the project has to be compiled with the /unsafe switch on.
要使用不安全的代码块，必须在打开 /unsafe 开关的情况下编译项目。
Open the properties for the project, go to the Buildtab and check the Allow unsafe codecheckbox.
打开项目的属性，转到Build选项卡并选中Allow unsafe code复选框。

To use unsafe code blocks, open the properties for the project, go to the Buildtab and check the Allow unsafe codecheckbox, then compile and run.
要使用不安全代码块，请打开项目的属性，转到“构建”选项卡并选中“允许不安全代码”复选框，然后编译并运行。
class myclass

int iData = 10;
int* pData = &iData;
Console.WriteLine("Data is " + iData);
