上传文件时出错 [英] error in uploading file

问题描述

我在上传文件时设置错误...在我的本地计算机上工作正常，但是当我将其放在服务器上时出现错误
以下是错误:-

System.IO.DirectoryNotFoundException:找不到路径"D:\ Websites \ enefinder.com \ httpdocs \ html \ uploadfiles \ 2-2-2010-20-12-49-807icon.JPG"的一部分. System.IO.FileStream.Init(字符串路径，FileMode模式，FileAccess访问，Int32权限，布尔useRights，FileShare共享，Int32 bufferSize，FileOptions选项，SECURITY_ATTRIBUTES secAttrs) ，位于System.IO.FileStream..ctor处的字符串，msgPath，布尔bFromProxy)(位于System.IO.FileStream..ctor处的字符串路径，FileMode模式，FileAccess访问，FileShare共享，Int32 bufferSize，FileOptions选项，字符串msgPath，布尔bFromProxy). (字符串路径，FileMode模式)位于html_upload.btnUpload_Click(对象发送方，EventArgs e)处，位于System.Web.HttpPostedFile.SaveAs(字符串文件名)

为什么使用这个地址D:\ Websites

我的代码是

filename = System.IO.Path.GetFileName(filename);
FileUpload1.PostedFile.SaveAs(Server.MapPath("uploadfiles")+"\\" + d2 + filename);

path ="uploadfiles" +"\\" + d2 +文件名；
SqlConnection con =新的SqlConnection(); con.ConnectionString = ConfigurationManager.ConnectionStrings ["abc"].ConnectionString;
SqlCommand cmd =新的SqlCommand();
cmd.CommandText =插入ProCat(url)VALUES(""+ path +")";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
con.Open();
int结果= cmd.ExecuteNonQuery();
con.Close();
如果(结果> 0)

Response.Redirect("upload.aspx");

请帮助...

path = "uploadfiles" + "\\" + d2 + filename;

这真是丑陋.请改用Path.Combine.

This is damn ugly. Use Path.Combine instead.

FileUpload1.PostedFile.SaveAs(Server.MapPath("uploadfiles") + "\\"+ d2 + filename );

这行是否给出错误?你不说

Does this line give the error ? You don''t say.

真正的问题是，是什么使您相信此目录存在?该错误表明它没有.

The real question is, what makes you believe this directory exists ? The error says it does not.
