c# 调用c++ .dll

首先导入命名空间using System.Runtime.InteropServices;

 

 

 1         string decodeStr = string.Empty;
 2         [DllImport("DataDeCode.dll", CharSet = CharSet.Ansi)]  // 插入dll文件 dll文件必须放在bin文件夹下
 3         public static extern void DataDeCode(GetSingeMobile func, string Input);
 4         //回调委托
 5         public delegate void GetSingeMobile(string str);
 6 
 7         public void decode_call_back(string str)  
 8         {
 9             if (str.Length > 10)
10             {
11                 decodeStr = str;
12             }
13         }

 

 

// 调用方法
GetSingeMobile func = new GetSingeMobile(decode_call_back);
DataDeCode(func, result);
