【问题描述】:
我在 ASP.NET 视图中声明了一个 DataGrid,我想生成一些 C# 代码以使用 Excel 电子表格 (.xlsx) 填充所述 DataGrid。这是我的代码:
<asp:DataGrid id="DataGrid1" runat="server"/>
<script language="C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\FileName.xlsx;Extended Properties=""Excel 12.0;HDR=YES;""";
// Create the connection object
OleDbConnection oledbConn = new OleDbConnection(connString);
try
{
// Open connection
oledbConn.Open();
// Create OleDbCommand object and select data from worksheet Sheet1
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [sheetname$]", oledbConn);
// Create new OleDbDataAdapter
OleDbDataAdapter oleda = new OleDbDataAdapter();
oleda.SelectCommand = cmd;
// Create a DataSet which will hold the data extracted from the worksheet.
DataSet ds = new DataSet();
// Fill the DataSet from the data extracted from the worksheet.
oleda.Fill(ds, "Something");
// Bind the data to the GridView
DataGrid1.DataSource = ds.Tables[0].DefaultView;
DataGrid1.DataBind();
}
catch
{
}
finally
{
// Close connection
oledbConn.Close();
}
}
</script>
当我运行该网站时,什么都没有发生。什么给了?
【问题讨论】:
-
您确定没有收到错误消息吗? - 你的 catch 块中没有任何代码
-
要在 try/catch/finally 块中使用 finally,您不需要指定 catch 块......所以 try/finally 就足够了,因此如果发生任何错误,它们会冒泡......
