c#调用CopyMemory api函数

[茂十茂]

[DllImport("kernel32.dll",EntryPoint="CopyMemory" ,SetLastError=true)]
internal static extern void CopyMemory(int Destination,byte Source,long Length);

以上为API声明

下面为调用，但出错，错在哪里呢？

         byte[] pbyteImageBuffer;
        int lAddrImage;

        dwBufferSize = dwWidth * dwHeight;
        pbyteImageBuffer=new byte[dwBufferSize];  
 
        axFvxImage1.GetImageAdrs(out lAddrImage, 0);
        CopyMemory(lAddrImage, pbyteImageBuffer[0], dwBufferSize);

谢谢net5i,我用Mershal.Copy OK了，但我担心用这个会不会有问题，因为网上说这个不太好用。

Marshal.Copy(pbyteImageBuffer,0,(IntPtr)lAddrImage,(int)dwBufferSize);

[DllImport("kernel32.dll",EntryPoint="CopyMemory" ,SetLastError=true)]
internal static extern void CopyMemory(IntPtr Destination,IntPtr Source, uint Length);

???

try
System.Runtime.InteropServices.Marshal.Copy()

Copies data from a managed array to an unmanaged memory pointer, or from an unmanaged memory pointer to a managed array.

.NET已经封装了内存拷贝方法，搂主可以直接调用的：Marshal.Copy
