C＃：“找不到编译动态表达式所需的一种或多种类型”

Question

我复制代码以从Excel文件中删除标题。我在以下代码中出现错误：

Microsoft.Office.Interop.Excel.Worksheet clsWorksheet =
                 (Excel.Worksheet)clsWorkbook.ActiveSheet;

错误是：

One or more types required to compile a dynamic expression cannot be found. Are you missing a reference?

我该如何解决？

Answer 1

Are you missing a reference?您需要向项目中添加Excel库（.dll）。如果已安装Excel，则应该能够找到“ Microsoft Excel 11.0对象库”
