C# 调用C写的DLL时 对应的int* 类型返回值转化为 IntPtr

C中代码：

[cpp] view plain copy

1. int* read(char*filename)
2. {
3. .......
4. }

C#中代码：

[csharp] view plain copy

1. [DllImport("myC.dll",EntryPoint="read",CharSet=CharSet.Auto)]
2. publicstaticextern IntPtr read(refbytefilename);

调用示例：

[csharp] view plain copy

1. stringname=@"d:\result\Gaussian_6_0.3.jpg";
2. byte[]filename=newbyte[100];
3. for(inti=0;i<name.Length;i++)
4. {
5. filename[i]=(byte)name[i];
6. }
   
7. IntPrt data = new IntPtr();
   
8. data = liblept168.read(reffilename[0]);
