从 C# 调用 Excel 宏时出错

Question

我正在尝试使用C# 4.5 从 Excel 文件中调用宏。我的 Excel 版本是 2010。

当我尝试调用宏时，出现以下错误：

Cannot run the macro 'MacroName'. The macro may not be available in this workbook or all macros may be disabled.

我为此搜索了很多，但似乎没有任何效果。

我已打开宏安全性，如以下屏幕截图所示：

我使用的代码如下：

Excel.Application book = null;
Excel.Workbooks workbooks = null;
Excel.Workbook macroWorkbook = null;
Excel.Workbook destinationWorkbook = null;

try
{
    book = new Excel.Application();

    workbooks = book.Workbooks;
    macroWorkbook = workbooks.Open(@"D:\Work\Macros.xls");
    destinationWorkbook = workbooks.Open(@"D:\Work\Destination.xlsx");

    book.Run("MacroName");

    macroWorkbook.Close(false);
    destinationWorkbook.Close(true);
}
catch (Exception ex)
{
    throw ex; // the finally will be executed before this is thrown
}
finally
{
    book.Quit();

    System.Runtime.InteropServices.Marshal.ReleaseComObject(macroWorkbook);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(destinationWorkbook);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(workbooks);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(book);

    macroWorkbook = null;
    destinationWorkbook = null;
    workbooks = null;
    book = null;
}

实际的宏存储在Macros.xls 中，并将在Destination.xslx 上运行。当我在Excel 本身中运行这个宏时，没有问题。

Answer 1

book.Run ("'Macros.xls'!MacroName");
