如何在c#中将excel值设置为datagrid？

using Microsoft.Office.Interop.Excel;
using System.Data;

var excelApp = new Application();

var excelWorkbook = excelApp.Workbooks.Open(@"C:\path\to\your\excel.xlsx");

var excelWorksheet = excelWorkbook.Worksheets["Sheet1"];
var range = excelWorksheet.UsedRange;
var data = range.Value as object[,];

var dataTable = new DataTable();

// 添加列
for (int i = 1; i <= range.Columns.Count; i++)
{
    dataTable.Columns.Add("Column " + i);
}

// 添加行
for (int row = 1; row <= range.Rows.Count; row++)
{
    var dataRow = dataTable.NewRow();
    for (int column = 1; column <= range.Columns.Count; column++)
    {
        dataRow[column - 1] = data[row, column];
    }
    dataTable.Rows.Add(dataRow);
}

excelWorkbook.Close();
excelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(excelWorksheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(excelWorkbook);
System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);

dataGrid.DataSource = dataTable;
