C# 使用C脚本和NAnt将文件复制到远程计算机（指定的登录会话不存在）

我目前正在使用TeamCity服务器上运行的NAnt和C编写一个脚本，用于在远程计算机上创建和部署MSI文件。远程计算机设置了一个共享文件夹，TeamCity服务器将通过脚本连接到该文件夹并将MSI文件复制到其中。我第一次运行它时它就可以正常工作了

但是当我第二次运行脚本时，当它试图连接到远程计算机上的共享时，它抛出一个异常，并显示以下消息：

"A specified logon session does not exist. It may already have been terminated."

我使用来自线程的解决方案，使用登录证书将MSI文件从TeamCity服务器复制到远程计算机

以下是我的NAnt文件中的C脚本，它进行文件复制：

//Script main entry point
public static void ScriptMain(Project project)
{
    NetworkCredential deployTargetCridentials = new NetworkCredential(project.Properties["deploy.remotesvr.username"],
                                                                        project.Properties["deploy.remotesvr.password"]);

    string connection = @"\\" + project.Properties["deploy.remotesvr"] + project.Properties["deploy.remotesvr.sharepath"];

    string sourceFile = project.Properties["wix.output.dir"] + @"\" + project.Properties["wix.output.file"] + ".msi";
    string destinationFile = @"\\" + project.Properties["deploy.remotesvr"] +
                                        project.Properties["deploy.remotesvr.sharepath"] + @"\" +
                                        project.Properties["deploy.remotesvr.deployfile"];

    //Copy installation file to deploy share
    Copy(project
            , project.Properties["wix.output.dir"]
            , project.Properties["wix.output.file"] + ".msi"
            , @"\\" + project.Properties["deploy.remotesvr"] + project.Properties["deploy.remotesvr.sharepath"]
            , project.Properties["deploy.remotesvr.deployfile"]
            , deployTargetCridentials);

}


//Copy MSI
public static void Copy(Project project, string sourcePath, string sourceFile, string destinationPath, string destinationFile, NetworkCredential cridentials)
{
    string source = sourcePath + @"\" + sourceFile;
    string destination = destinationPath + @"\" + destinationFile;

    try
    {
        project.Log(Level.Info, " ");
        project.Log(Level.Info, "Copying " + source + " to " + destination);

        project.Log(Level.Info, "  Connecting to copy share: " + destinationPath);
        using (new NetworkConnection(destinationPath, cridentials))
        {
            project.Log(Level.Info, "  Copying file");
            File.Copy(source, destination, true);
        }
        project.Log(Level.Info, "Copy successfull!");
    }
    catch (Exception ex)
    {
        project.Log(Level.Warning, "WARNING: Could not copy file: " + ex.Message.ToString().Trim().Replace("\r\n", ""));
    }

副本中的下一行出现异常

using (new NetworkConnection(destinationPath, cridentials))

当我试图在测试应用程序中运行相同的复制代码时，它每次都复制文件。只有当我在脚本中运行它时，才会发生异常

有人知道这是为什么吗？

在打开新连接之前，您是否尝试过测试/关闭任何现有连接？

我尝试过在NetworkConnection的Dispose中删除对OwntcancelConnection2的调用，这导致它可以正常工作。因此，如果我取消连接，它会给我一个指定的登录会话不存在。它可能已经被终止了。第二次尝试打开与同一台计算机的连接时出错。我现在不太明白为什么..您是否也尝试连接\u更新\u配置文件而不是0？
