C#数据类型的问题紧急
有DLL中函数如下
int IFV_Verify(unsigned char * pFeatureS, unsigned int nSizeOfS, unsigned char * pFeatureT, unsigned int nSizeOfT, int nLevel);
怎么转化成C#中的数据类型谢谢。

[解决办法]
public static extern Int32 IFV_Verify(string pFeatureS, int nSizeOfS, string pFeatureT, int nSizeOfT, int nLevel);

如果不行，再把int n改成uint试一试！

[解决办法]
using System.Runtime.InteropService;
[DllImport( "dllname.dll ")]
public static extern int IFV_Verify(string pFeatureS, int nSizeOfS, string pFeatureT, int nSizeOfT, int nLevel);
