c# - 如何重命名 "using Directive"C#

Question

您将如何使用 C# 重命名“使用指令”？

因为有时候你从某个地方复制一个类(下面的例子)

//Other Code
        Excel.ApplicationClass excel;
        Excel.Workbooks workbooks;
        Excel.Workbook workbook;
        Excel.Worksheet worksheet;
        Excel.Sheets worksheets;
//Other Code

而不是将所有内容重命名为

//Other Code
        Microsoft.Office.Interop.Excel.ApplicationClass excel;
        Microsoft.Office.Interop.Excel.Workbooks workbooks;
        Microsoft.Office.Interop.Excel.Workbook workbook;
        Microsoft.Office.Interop.Excel.Worksheet worksheet;
        Microsoft.Office.Interop.Excel.Sheets worksheets;
//Other Code

所以有类似的东西

Using  Microsoft.Office.Interop.Excel.ApplicationClass as 'Excel'

Answer 1

您可以像这样创建别名:

// for whole namespace
using Excel = Microsoft.Office.Interop.Excel;
// use like this
Excel.ApplicationClass excel = /* ... */;

// or for single type
using ExcelApp = Microsoft.Office.Interop.Excel.ApplicationClass;
// use like this
ExcelApp excel = /* ... */;
