这句话有什么问题? [英] What's the problem in this statement?

问题描述

大家好，我正在做一个示例应用程序，将DOC文件转换为PDF.这样做时出现错误.

Hi everyone, I am doing a sample application to convert the DOC file into PDF. While doing this I''m getting an error.

//Creating the instance of WordApplication
MSDOC = new Microsoft.Office.Interop.Word.ApplicationClass();
try
{
    MSDOC.Visible = false;
    MSDOC.Documents.Open(ref Source, ref Unknown,
        ref Unknown, ref Unknown, ref Unknown,
        ref Unknown, ref Unknown, ref Unknown,
        ref Unknown, ref Unknown, ref Unknown,
        ref Unknown, ref Unknown, ref Unknown,
        ref Unknown, ref Unknown);
    MSDOC.Application.Visible = false;
    MSDOC.WindowState = Microsoft.Office.Interop.Word.WdWindowState.wdWindowStateMaximize;
    object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message, "Message from Sample");
}

在此声明中，我得到了一个错误:

At this statement I am getting an error:

object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;

错误:无法嵌入互操作类型"Microsoft.Office.Interop.Word.ApplicationClass".请改用适用的接口.

Error: Interop type ''Microsoft.Office.Interop.Word.ApplicationClass'' cannot be embedded. Use the applicable interface instead.

推荐答案

请尝试以下操作:

Try this:

Microsoft.Office.Interop.Word.Application MSDOC;
MSDOC = new Microsoft.Office.Interop.Word.Application();

祝你好运！

Good luck!
