在我的ASP.NET WEbForms应用中,我想创建一个文件夹并在其中保存文件。在我的项目中,我有一个名为CRMImages/Projects的文件夹。我想在Projects文件夹&中创建一个子文件夹。保存他们的图像。目前,我从CRMImages /检索图像作为父文件夹。

这是我在代码隐藏方面的代码:

                try
                {
                    string pathToCreate = "~/CRMImages/Projects/" + item.ProjectId;
                    string myFileName = "";
                    if (!Directory.Exists(Server.MapPath(pathToCreate)))
                    {
                        DirectoryInfo di = Directory.CreateDirectory(pathToCreate);
                        var user = System.Security.Principal.WindowsIdentity.GetCurrent().User;
                        var userName = user.Translate(typeof(System.Security.Principal.NTAccount));
                        System.Security.AccessControl.DirectorySecurity sec = di.GetAccessControl();
                        sec.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule(userName,
                            System.Security.AccessControl.FileSystemRights.Modify,
                            System.Security.AccessControl.AccessControlType.Allow));
                        di.SetAccessControl(sec);
                        Directory.CreateDirectory(pathToCreate);

                        System.Diagnostics.Debug.WriteLine("FOLDER CREATED PATH : " + di.FullName);
                        myFileName = pathToCreate + "/projectLogo.png";
                        System.Diagnostics.Debug.WriteLine("PATH To Save Logo File & NAME : " + myFileName);

                        /*
                        if (File.Exists(item.ProjectLogoUrl) ) {
                            FileUpload projLogoUpload = new FileUpload();
                            if (projLogoUpload.HasFile) {
                                myFileName = pathToCreate + "/projectLogo.png";
                                projLogoUpload.SaveAs(myFileName);
                            }
                            // panFileBtn.SaveAs(filePath);
                        }  */
                    }
                }
                catch (Exception ex)
                {
                    System.Diagnostics.Debug.WriteLine("EXCEPTION While SAving File : " + ex.Message + "\n *** STACK" + ex.StackTrace);
                }  

代码执行,但我没有在项目文件夹中看到创建的文件夹。让我们说item.ProjectId的值是“EMP3”,我在上面的代码执行中看到的日志是:

FOLDER CREATED PATH : C:\Program Files (x86)\IIS Express\~\CRMImages\Projects\EMP3
PATH To Save Logo File & NAME : ~/CRMImages/Projects/EMP3/projectLogo.png

我查看了IIS Express文件夹&在那里创建了这个完整的路径。你能说出为什么在IISExpress&如何在我的项目中已存在的/CRMImages/Projects文件夹中创建文件夹!!

非常感谢任何帮助。 感谢

你必须替换下面的行

DirectoryInfo di = Directory.CreateDirectory(pathToCreate);

使用

DirectoryInfo di = Directory.CreateDirectory(Server.MapPath(pathToCreate));
