疑难问题啊!数据拷贝
[DllImport("kernel32", EntryPoint = "RtlMoveMemory", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
private static extern void CopyMemory(object Destination, object Source, long Length);


private static string aa(byte[] fbytFile)
{
  dim dbl as double
  CopyMemory(ByVal VarPtr(dbl), ByVal VarPtr(fbytFile(0)) + 90, 8)
}

这是VB6的一段代码.调用了一个API.

哪位帮下我,写成C#要怎么写啊

------解决方案--------------------
private static string aa(byte[] fbytFile) --->VB是这样吗?
{ 
double dbl ;
CopyMemory(object VarPtr(dbl), object (VarPtr(fbytFile(0)) + 90), 8) ;
} 
private static void CopyMemory(object Destination, object Source, long Length); 


------解决方案--------------------
参考如下代码

C# code

[DllImport("kernel32", EntryPoint = "RtlMoveMemory")]
private static extern void CopyMemory(
    IntPtr destination, IntPtr source, int length); 

private static string aa(byte[] fbytFile) 
{ 
    double[] dbl = new double[1];
    CopyMemory(Marshal.UnsafeAddrOfPinnedArrayElement(dbl, 0), 
        Marshal.UnsafeAddrOfPinnedArrayElement(fbytFile, 0), 
        Marshal.SizeOf(typeof(double)));
    return dbl[0].ToString();
} 

private void button1_Click(object sender, EventArgs e)
{
    double[] d = new double[] { 20071009 };
    byte[] b = new byte[8];
    Buffer.BlockCopy(d, 0, b, 0, 8);
    Text = aa(b);
}
