wpf创建一个词典，键为excel的第一列中的数字，值为excel第二列的字符串

可以按照以下步骤来创建一个词典：

1. 引入以下命名空间：

   using System.Collections.Generic;
   using Microsoft.Office.Interop.Excel;

2. 声明一个 Dictionary 变量：

   Dictionary<int, string> dict = new Dictionary<int, string>();

3. 打开 Excel 文件并获取工作表：

   Application excel = new Application();
   Workbook workbook = excel.Workbooks.Open("excel文件路径");
   Worksheet worksheet = workbook.Sheets[1];

4. 遍历 Excel 的第一列和第二列，并将它们作为键值对添加到词典中：

   int row = 1;
   while (!string.IsNullOrEmpty(worksheet.Cells[row, 1].Text))
   {
       int key = (int)worksheet.Cells[row, 1].Value;
       string value = worksheet.Cells[row, 2].Text;
       dict.Add(key, value);
       row++;
   }

5. 关闭 Excel 文件：

   workbook.Close();
   excel.Quit();

完整代码示例：

using System.Collections.Generic;
using Microsoft.Office.Interop.Excel;

// ...

Dictionary<int, string> dict = new Dictionary<int, string>();

Application excel = new Application();
Workbook workbook = excel.Workbooks.Open("excel文件路径");
Worksheet worksheet = workbook.Sheets[1];

int row = 1;
while (!string.IsNullOrEmpty(worksheet.Cells[row, 1].Text))
{
    int key = (int)worksheet.Cells[row, 1].Value;
    string value = worksheet.Cells[row, 2].Text;
    dict.Add(key, value);
    row++;
}

workbook.Close();
excel.Quit();
