c# 本地文件上传到服务器

1、先把服务器上的路径设置成共享路径

2、代码如下

    string fileName = "5002356611"; // 替换为你要查找的文件名
    string aaa = @"E:\SAP图片"; // 替换为源文件夹的路径
    string b = @"\\173.1.60.169\test";// 替换成实际的网络路径（该路径必须是共享文件夹）
    var state = ConnectState(b, "账号", "密码");//访问网路共享路径的账号密码

     if (state == false)
     {
            //无法连接服务器
      }
    CopyFileByFileName(fileName, aaa, b);
    string bwer = string.Empty;
    CloseState(b, out bwer);

　　 bool CopyFileByFileName(string fileName, string sourcePath, string destinationPath)
    {
        string[] matchingFiles = Directory.GetFiles(sourcePath, fileName + ".*");

        if (matchingFiles.Length > 0)
        {
            string sourceFilePath = matchingFiles[0];
            string destinationFilePath = Path.Combine(destinationPath, Path.GetFileName(sourceFilePath));

            CopyFile(sourceFilePath, destinationFilePath);
            
            //Console.WriteLine($"文件已成功从 {sourceFilePath} 复制到 {destinationFilePath}");
        }
        else
        {
            return false;
            // Console.WriteLine($"未找到匹配的文件");
        }
        return true;
    }

    void CopyFile(string sourcePath, string destinationPath)
    {
        File.Copy(sourcePath, destinationPath, true);
    }
    public void CopyFolder(string sourceFolder, string destFolder)
    {
        //如果目标路径不存在,则创建目标路径
        if (!Directory.Exists(destFolder))
        {
            Directory.CreateDirectory(destFolder);
        }
        //得到原文件根目录下的所有文件
        string[] files = Directory.GetFiles(sourceFolder);
        foreach (string file in files)
        {
            string name = Path.GetFileName(file);
            string dest = Path.Combine(destFolder, name);
            File.Copy(file, dest);//复制文件           
                                  //if (files.Count() != 0)
                                  //{
                                  //    progressBar.Value += 1;
                                  //}

        }
        //得到原文件根目录下的所有文件夹
        string[] folders = Directory.GetDirectories(sourceFolder);
        foreach (string folder in folders)
