C# 多文件上传并将其转换为html格式

我试图上传多个文件，并通过将它们放入for循环，将它们同时转换为

.html

格式。多个文件上载完成并存储到“上载”文件中，但只有第一个文件转换为

.htm

格式，而不是全部

这是我的密码：

protected void btnUpload_Click(object sender, EventArgs e)
    {

        HttpFileCollection fileCollection = Request.Files;
        //Code to check if user has selected any file on the form
        if (!(fUpload1.HasFile))
        {
            lblMessage1.Text = "Please choose file to upload";
        }
        else
        {
            for (int i = 0; i < fileCollection.Count; i++)
            {
                try
                {
                    HttpPostedFile uploadfile = fileCollection[i];
                    string fileName = System.IO.Path.GetFileName(uploadfile.FileName);

                    //To check the file extension if it is word document or something else
                    //string strFileName = fUpload1.FileName;
                    string[] strSep = fileName.Split('.');
                    int arrLength = strSep.Length - 1;
                    string strExt = strSep[arrLength].ToString().ToUpper();

您不能使用asp.net中的一个文件上载控件上载多个文件

请检查此处以获取解决方案： 及

---

或者，要上载多个文件，您可以在客户端生成多个上载控件或创建用户定义的控件。

您正在使用Interop转换文档文件-，这就是

---

您可以使用其他库，如（免费）或（商业），这些库不依赖Office，并且在您的服务器场景中完全受支持。

如果目录中存在上载的文件，则使用directory.GetFiles代替httpfilecollection。它将从目录中返回案例中的特定文件*.doc文件，然后将其转换为.html

string[] filePaths = Directory.GetFiles(@"d:\files\", "*.doc");

我是c#的初学者。。。所以，如果你能指出我在代码中犯了什么错误的话..上传成功并存储在文件夹“Upload”中.但是只有第一个文档文件被转换成.htm格式谢谢..我会调查的
