如何使用ASP .NET将所选文件转换为wav格式 [英] How to convert the selected files to wav format using ASP .NET

问题描述

我需要开发一个使用文件上传器选择多个音频文件的Web应用程序，当我点击上传按钮时，音频文件应该转换为.wav格式，并且应该保存在应用程序文件夹中。我可以这样做吗。





以下是我在aspx页面中的代码

 <   h4  > 选择要上传的文件：<   / h4  >  
 
 <   asp：FileUpload     ID   =  FileUpload1    AllowMultiple   =   true  
   
                       runat   =  server >  <   / asp：FileUpload  >  
 
 <   br  < span class =code-attribute>   /  >  
 <   br     /  >  
 
 < ;   asp：按钮    ID   =  UploadBtn  
   
                      文字  = 上传文件  
   
                       OnClick   =  UploadBtn_Click  
   
                       runat   = 服务器 >  <   / asp：按钮 >  
 
 <   hr     /  >  
 
 <   asp：标签    ID   =  UploadStatusLabel  
   
              < span class =code-attribute>         runat   =  server >  
 <  < span class =code-leadattribute> / asp：Label  >  

以下是我在.cs页面的代码

  protected   void  UploadBtn_Click（ object  sender，EventArgs e）
 {
 < span class =code-comment> //  指定服务器上的路径 
  //  将上传的文件保存到。 
  string  savePath =  @  c：\ temp \ uploads; 
 
  //  在尝试保存文件之前，请确认 
  //   FileUpload控件包含文件。 
  if （FileUpload1.HasFile）
 {
  //  获取名称要上传的文件。 
  string  fileName = Server.HtmlEncode（FileUpload1.FileName）; 
 
  //  获取上传文件的扩展名。 
  string  extension = System.IO.Path.GetExtension（fileName）; 
 
  //  仅允许带有.ds2或.dss扩展名的文件 
  //  上传。 
  if （（extension ==  。ds2）||（extension == < span class =code-string> 。ds2）||（extension ==  。m4a））
 {
  //  附加要上传到路径的文件的名称。 
 savePath + = fileName; 
 
  //  调用SaveAs方法保存 
 < span class =code-comment> //  将文件上传到指定路径。 
  //  此示例不执行所有 
  //  必要的错误检查。 
  //  如果文件包含同名 
  //  已存在于指定路径中， 
  //  上传的文件会覆盖它。 
 FileUpload1.SaveAs（savePath）; 
 
  //  通知用户他们的文件已成功上传。 
 UploadStatusLabel.Text =  您的文件已成功上传。; 
} 
 其他 
 {
  //  < span class =code-comment>通知用户他们的文件未上传的原因。 
 UploadStatusLabel.Text =  您的文件未上传，因为 + 
  它没有有.ds2或.dss扩展名。; 
} 
 
} 
 
}

I need to develop a web application which selects multiple audio files using file uploader and when i click on upload button the audio files should get converted to .wav format and should get saved in the application folder.how can i do this.


Below is my code in aspx page page

<h4>Select a file to upload:</h4>

      <asp:FileUpload ID="FileUpload1" AllowMultiple="true"

          runat="server"></asp:FileUpload>

      <br />
      <br />

      <asp:Button ID="UploadBtn"

          Text="Upload file"

          OnClick="UploadBtn_Click"

          runat="server"></asp:Button>

      <hr />

      <asp:Label ID="UploadStatusLabel"

          runat="server">
      </asp:Label>

Below is my code in .cs page

protected void UploadBtn_Click(object sender, EventArgs e)
{
    // Specify the path on the server to
    // save the uploaded file to.
    string savePath = @"c:\temp\uploads";

    // Before attempting to save the file, verify
    // that the FileUpload control contains a file.
    if (FileUpload1.HasFile)
    {
        // Get the name of the file to upload.
        string fileName = Server.HtmlEncode(FileUpload1.FileName);

        // Get the extension of the uploaded file.
        string extension = System.IO.Path.GetExtension(fileName);

        // Allow only files with .ds2 or .dss extensions
        // to be uploaded.
        if ((extension == ".ds2") || (extension == ".ds2")  || (extension == ".m4a"))
        {
            // Append the name of the file to upload to the path.
            savePath += fileName;

            // Call the SaveAs method to save the
            // uploaded file to the specified path.
            // This example does not perform all
            // the necessary error checking.
            // If a file with the same name
            // already exists in the specified path,
            // the uploaded file overwrites it.
            FileUpload1.SaveAs(savePath);

            // Notify the user that their file was successfully uploaded.
            UploadStatusLabel.Text = "Your file was uploaded successfully.";
        }
        else
        {
            // Notify the user why their file was not uploaded.
            UploadStatusLabel.Text = "Your file was not uploaded because " +
                                     "it does not have a .ds2 or .dss extension.";
        }

    }

}

What I have tried:
