Marshal.Copy在对有C++代码和C#代码混合的项目中很有用，它能在非托管指针和托管数组间起到相互转换作用。 Namespace: System.Runtime.InteropServices Assembly: mscorlib (in mscorlib.dll) Copies data from a managed array to an unmanaged memory pointer, or from an unmanaged memory pointer to a managed array. 把数据从一个托管的数组拷贝到一个非托管的内存指针， 或从一个非托管的内存指针拷贝到一个托管的数组。 Marchal.Copy有很多形态，其四个参数有很多类型变化： Copy(array<Byte>[]()[], Int32, IntPtr, Int32) Copy(array<Char>[]()[], Int32, IntPtr, Int32) Copy(array<Double>[]()[], Int32, IntPtr, Int32) Copy(array<Int16>[]()[], Int32, IntPtr, Int32) Copy(array<Int32>[]()[], Int32, IntPtr, Int32) Copy(array<Int64>[]()[], Int32, IntPtr, Int32) [...]
