c#重新命名檔案 – 拋棄MoveTo,而引用vc 中rename產生rename.dll

1：vc6中建立win32 簡單動態連結程式庫

2：添加Rename.cpp檔案，如下：

 

#include <string>
#include <stdlib.h>
using namespace std;

extern "C" int  _declspec(dllexport) renamefile(char *_oldname,char * _newname);

int renamefile(char* _oldname,char* _newname) 
{
    char oldname[1000], newname[1000];  
    strcpy(oldname,_oldname);
 strcpy(newname,_newname);
    if (rename(oldname, newname) == 0) 
       return 0;
    else 
       return 1; 
}

3：產生Rename.dll

4：在C#中調用

複製Rename.dll到應用程式BIN目錄下

 C#程式：

using System.Runtime.InteropServices;

namespace WinApp
{
    public partial class Form4 : Form
    {
        [DllImport("Rename.dll", EntryPoint = "renamefile")]
        public static extern int renamefile(string source, string dest);
        public Form4()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Text = renamefile(@"c:\1.txt", @"c:\2.txt").ToString();
        }
    }
}
