           string name = fi.Name;
           string Extension = fi.Extension;
           BAL_ObjectsCCRM.BO_Scripts objbo = new BAL_ObjectsCCRM.BO_Scripts();
           objbo.Content_Name = Document_Content;
           objbo.File_Name = name;

推荐答案

你不能使用FileInfo，因为服务器上不存在该文件。如果要提取名称和扩展名，请使用System.IO.Path



Path.GetFileName Method（System.IO）| Microsoft Docs [ ^ ]



Path.GetExtension Method（System.IO）| Microsoft Docs [ ^ ]

You can't use FileInfo because the file doesn't exist on the server. If you want to extract the name and extension then use System.IO.Path

Path.GetFileName Method (System.IO) | Microsoft Docs[^]

Path.GetExtension Method (System.IO) | Microsoft Docs[^]
