Question

编辑：因此，我现在已经获得了该网络文件夹的服务帐户“ docwriter”和密码“ password”。我创建了一个类ConnectionToNetworkFolder，并尝试了几次尝试来使用它。但是仍然没有成功。尝试将pdf文件保存在网络的路径目录中时遇到问题，但是保存到本地文件夹时工作正常。见文章底部，我包括了我的课程和我的页面

原始帖子：我已经尝试过几个显示的代码。我还更改了网络文件夹的安全权限，以添加“网络服务”（在线），并具有修改，读取和执行，列出文件夹内容，读取，写入的权限（我是否需要特殊权限或完全控制权？）。我在做什么错了？

***本地文件夹：成功

            Telerik.Reporting.Processing.ReportProcessor reportProcessor = new ReportProcessor();
            RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

            string documentName = ProductionInstructionPrintPage.plantCode + ProductionInstructionPrintPage.machine + ProductionInstructionPrintPage.ordNum;
            string filePath = @"C:\Users\Lily\Desktop\SavingPdfTesting";
            string fileName = documentName + "." + result.Extension;
            string full_path = filePath + fileName;

            //writes the pdf to disk
            using (FileStream fs = new FileStream(full_path, FileMode.Create))
            {
                fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
            }

***网络尝试1：失败-访问被拒绝

            Telerik.Reporting.Processing.ReportProcessor reportProcessor = new ReportProcessor();
            RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

            string documentName = ProductionInstructionPrintPage.plantCode + ProductionInstructionPrintPage.machine + ProductionInstructionPrintPage.ordNum;
            string filePath = @"\\testing.company.com\reports\";
            string fileName = documentName + "." + result.Extension;
            string full_path = filePath + fileName;

            //writes the pdf to disk
            using (FileStream fs = new FileStream(full_path, FileMode.Create))
            {
                fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
            }

这是我的ConnectionToNetworkFolder类：

class ConnectionToNetworkFolder : IDisposable
    {
        string _networkName;

        public ConnectionToNetworkFolder(string networkName, NetworkCredential credentials)
        {
            _networkName = networkName;


            var netResource = new NetResource()
            {
                Scope = ResourceScope.GlobalNetwork,
                ResourceType = ResourceType.Disk,
                DisplayType = ResourceDisplaytype.Share,
                RemoteName = networkName
            };

            var userName = string.IsNullOrEmpty(credentials.Domain)
                ? credentials.UserName
                : string.Format(@"{0}\{1}", credentials.Domain, credentials.UserName);

            var result = WNetAddConnection2(
                netResource,
                credentials.Password,
                userName,
                0);

            if (result != 0)
            {
                throw new Win32Exception(result, "Error connecting to remote share");
            }
        }

        ~ConnectionToNetworkFolder()
        {
            Dispose(false);
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }

        protected virtual void Dispose(bool disposing)
        {
            WNetCancelConnection2(_networkName, 0, true);
        }

        [DllImport("mpr.dll")]
        private static extern int WNetAddConnection2(NetResource netResource,

        public string LocalName;
        public string RemoteName;
        public string Comment;
        public string Provider;
    }

    public enum ResourceScope : int

我的页面：声明凭证变量：

        NetworkCredential credentials = new NetworkCredential(@"docwriter", "password");

点击事件功能：

   private void apprBtn_Click(object sender, EventArgs e)

            }
}

Answer 1

检查共享的权限。如您所述，您已向“网络服务”添加了权限，但是运行您的应用程序的用户是什么？

Answer 2

我的猜测是您需要模拟服务器上的文件访问。您可能没有足够的共享权限，因为您正在“写入”网络。

这里是有关如何模拟文件/文件夹访问的示例。它清楚地说明了您需要做什么。
Code Project UNC Access

在网络路径目录上创建文件时，C＃访问被拒绝
