我对 MVC 4 很陌生。我有一个场景，我需要在单独的类中定义一组方法并在控制器中调用所有这些方法。这样我就可以处理与视图不同的功能。

以下是我的代码示例......请查看。

我在控制器下添加了一个新的类文件并定义了如下方法：

 public void Convert(ConvertFileOutputType outputType, FileInfo inFile, DirectoryInfo        outFolder, int timeout,
        int topMargin, int bottomMargin, int leftMargin, int rightMargin)
    {
       switch (outputType)
        {
            case ConvertFileOutputType.Pdf:
                break;
            default: break;
            // throw new    ConvertFileException(Properties.Resources.OutputTypeNotSupportedWordPerfect);
        }
        if (converter == null)
        {
            //converter.LicenseKey = "";
            converter = new PdfConverter();
            converter.LicenseKey = "";
            converter.PdfDocumentOptions.LiveUrlsEnabled = false;
            converter.PdfDocumentOptions.PdfPageSize = PdfPageSize.Letter;
            converter.PdfDocumentOptions.TopMargin = topMargin;
            converter.PdfDocumentOptions.BottomMargin = bottomMargin;
            converter.PdfDocumentOptions.LeftMargin = leftMargin;
            converter.PdfDocumentOptions.RightMargin = rightMargin;
            converter.AvoidImageBreak = true;
        }
        converter.PdfDocumentInfo.AuthorName = "FileConvert";
        converter.PdfDocumentInfo.Title = inFile.Name;
        converter.PdfDocumentInfo.CreatedDate = DateTime.Now;
        converter.SavePdfFromHtmlFileToFile(inFile.FullName, outFolder + "\\" + inFile.Name + ".pdf");
    }

我想在控制器方法中调用上述方法....我盲目地将代码编写为....

  public string UploadAsPDF(HttpPostedFileBase fileData)
     {
         var fileName = this.Server.MapPath("~/uploads/" +     System.IO.Path.GetFileName(fileData.FileName));
         fileData.SaveAs(fileName);


        Convert(outputType, inFile,outFolder,timeout, topMargin, bottomMargin, leftMargin, rightMargin);

         return "OK"; 
     }

每当我尝试构建它时，一个类型被用作方法请建议....

如果该Convert方法在一个名为的类中，则Converters需要instantiate该类，然后调用Convert....

public Converters {
   public void Convert(...);
}

然后你会像这样使用......

public string UploadAsPDF(HttpPostedFileBase fileData)
     {
         var fileName = this.Server.MapPath("~/uploads/" + System.IO.Path.GetFileName(fileData.FileName));
         fileData.SaveAs(fileName);


        var converters = new Converters();
        converters.Convert(outputType, inFile,outFolder,timeout, 
                           topMargin, bottomMargin, leftMargin, rightMargin);

         return "OK"; 
     }
