在asp.net中从excel中读取数据

我想在一个文本框中读取整个excel表单的数据。

这可能吗？

我知道从Excel中读取单元格数据到文本框的代码。

PrivateSub Button18_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button18.Click Dim xlaTest As Excel.Application = CType(CreateObject("Excel.Application"), Excel.Application) xlaTest.Visible = True Dim wbkTest As Excel.Workbook = xlaTest.Workbooks.Open("D:\Tests\VBTrials\ExcelTests\TestWorkbook.xls") Dim wshTest As Excel.Worksheet = DirectCast(wbkTest.Worksheets("Sheet1"), Excel.Worksheet) TextBox1.Text = wshTest.Range("B2").Value wbkTest.Close() xlaTest.Quit() EndSub 

Answer 1

 private List<object> Excelvoider() { Excel.Application xlApp = new Excel.Application(); Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:/Temp/Книга1.xlsx"); Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1]; Excel.Range xlRange = xlWorksheet.Range["B3", "Q58"]; List<object> stroke = new List<object>(); int rowCount = xlRange.Rows.Count; int colCount = xlRange.Columns.Count; for (int i = 1; i <= rowCount; i++) { for (int j = 1; j <= colCount; i++) { stroke.Add(xlRange.Value2[i, j]); } } return stroke; } 

这是一个单元格到另一个单元格的范围：

 Excel.Range xlRange = xlWorksheet.Range["B3", "Q58"]; 

你也可以使用xlWorksheet.UsedRange。
