上传发生错误！原因：System.NotSupportedException: 不支持给定路径的格式。 在 System.Security.Util.StringExpressionSet.CanonicalizePath(String path, Boolean needFullPath) 在 System.Security.Util.StringExpressionSet.CreateListFromExpressions(String[] str, Boolean needFullPath) 在 System.Security.Permissions.FileIOPermission.AddPathList(FileIOPermissionAccess access, AccessControlActions control, String[] pathListOrig, Boolean checkForDuplicates, Boolean needFullPath, Boolean copyPathList) 在 System.Security.Permissions.FileIOPermission..ctor(FileIOPermissionAccess access, AccessControlActions control, String[] pathList, Boolean checkForDuplicates, Boolean needFullPath) 在 System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath) 在 System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) 在 System.IO.FileStream..ctor(String path, FileMode mode) 在 System.Web.HttpPostedFile.SaveAs(String filename) 在 Cal_calUpload.btnUpload_Click(Object sender, EventArgs e)
------解决方案--------------------------------------------------------
string serverpath = Server.MapPath("images/") + filename;
打个断点看看这个长啥样。。
------解决方案--------------------------------------------------------
上传过程，首先你应该判断上传的本地文件是否存在？其次，设置上传支持文件的格式。然后，注意上传的协议方式（是Http还是ftp等），判断是否能够连接到服务器（能否ping得通）。最后，能够ping得通，上传到相应的服务器。
------解决方案--------------------------------------------------------
string serverpath = Server.MapPath("images/") + filename;你写成这个样子试试
string serverpath = Server.MapPath("images/"+ filename+"");
------解决方案--------------------------------------------------------
string serverpath = Server.MapPath("~/images/" + System.IO.Path.GetFileName(mypost.FileName)) ;
mypost.SaveAs(serverpath);
