求助：C#调用c++的dll，字符串传递问题

Answer 1

C#的定义
public static extern IntPtr run([MarshalAs(UnmanagedType.LPArray)]byte[] uml, [MarshalAs(UnmanagedType.LPArray)]byte[] name);

调用
byte[] buml = new byte[]｛｝;
byte[] bname = new byte[]｛｝;

string a="bcde";
string b="fghijk";
buml = System.Text.Encoding.ASCII.GetBytes(a);
bname = System.Text.Encoding.ASCII.GetBytes(b);

IntPtr intp = run(buml , bname );
