將DOC轉換爲PDF，錯誤：「不包含適用於入口點的靜態'Main'方法」

Question

我試圖使用此代碼將doc文件轉換爲pdf。我得到這個錯誤「不包含適用於入口點的靜態'主'方法」 我不確定這段代碼有什麼問題。感謝您的任何幫助。

Answer 1

每個應用程序都需要一個入口點代碼執行將開始。 C＃控制檯應用程序尋找一個名爲Main的靜態函數。

因此，假設您正在嘗試構建控制檯應用程序，則需要添加另一個類，如下所示。 （注：這是在命令行中的前兩個參數傳遞而不做任何驗證）

namespace WindowsFormsApplication4 { public static class Program { public static void Main(string[] args) { translate.ConvertWordFileToPdf(args[0], args[1]); } } }

Answer 2

我同意關於你的一個主要的靜態方法的需要dabron。

我假設您已將'translate'類添加到Windows窗體項目中，因爲您使用的是System.Windows.Forms命名空間。

當你創建一個雙贏的窗體項目上VS2010，你會發現一個名爲Program.cs的一個CS文件，其中應包括這樣一個類：

static class Program 
    { 
     /// <summary> 
     /// The main entry point for the application. 
     /// </summary> 
     [STAThread] 
     static void Main() 
     { 
      Application.EnableVisualStyles(); 
      Application.SetCompatibleTextRenderingDefault(false); 
      Application.Run(new Form1()); 
     } 
    } 
} 

如果你沒有一個你可以創建一個新的贏窗體項目，添加你的類文件。

祝你好運。
