C#如何实现上传和下载WORD文档

Question

private void upload_Click(object sender, System.EventArgs e)
{
string   fileName   =   file1.PostedFile.FileName;   
int   numberOfIt   =   fileName.LastIndexOf(@"\");   
if   (numberOfIt   >=   0)   
{   
fileName   =   fileName.Substring(numberOfIt+1);   
}   
string   newPath   =   @"c:\yours\"   +   fileName;   
File1.PostedFile.SaveAs(newPath);    }这段代码提示找不到FILE1，问题何在？是缺少USING指令集吗

Answer 1

file1.SaveAs(newPath);   你的大小写搞错了吧？你写的是 File1

Answer 2

大小写我改过来了，现在的问题是提示file1找不到，缺少USING指令

Answer 3

有没有将file1改成服务器端控件

Answer 4

    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            Boolean fileOK = false;
            String path = Server.MapPath("~/UploadedImages/");
            if (FileUpload1.HasFile)
            {
                String fileExtension =
                    System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();
                String[] allowedExtensions = 
                { ".doc"};
                for (int i = 0; i < allowedExtensions.Length; i++)
                {
                    if (fileExtension == allowedExtensions[i])
                    {
                        fileOK = true;
                    }
                }
            }            if (fileOK)
            {
                try
                {
                    FileUpload1.PostedFile.SaveAs(path
                        + FileUpload1.FileName);
                    Label1.Text = "File uploaded!";
                }
                catch (Exception ex)
                {
                    Label1.Text = "File could not be uploaded.";
                }
            }
            else
            {
                Label1.Text = "Cannot accept files of this type.";
            }
        }
    }
