我在開發asp.net 3.5中的web項目DataTable到Excel導出
我想導出數據表到Excel。但是在數據表中有20.000行。有時超時問題發生..
protected string Worksheet97_Header()
{
string s = "<tr>";
foreach (ExcelColumn col in Columns)
{
s += "<th>" + col.Header_Text + "</th>";
}
s+="</tr>";
return s;
}
protected string Worksheet97_Data()
{
string s = "";
try
{
for (int i = 0; i < data.Rows.Count; i++)
{
s += "<tr>";
foreach (ExcelColumn col in Columns)
{
if (col.Column_Type == "System.String")
s += "<td>" + data.Rows[i][col.Field_Name].ToString() + "</td>";
if (col.Column_Type == "System.DateTime")
s += "<td>" + Convert.ToDateTime(data.Rows[i][col.Field_Name]).ToString("dd.MM.yyyy HH:mm:ss") + "</td>";
if (col.Column_Type == "System.Int32")
s += "<td>" + data.Rows[i][col.Field_Name].ToString() + "</td>";
if ((col.Column_Type == "System.Double") |
(col.Column_Type == "System.Decimal") |
(col.Column_Type == "System.Int16") |
(col.Column_Type == "System.Int32") |
(col.Column_Type == "System.Int64"))
s += "<td>" + Convert.ToDouble(data.Rows[i][col.Field_Name]).ToString("0.00") + "</td>";
}
}
}
catch (Exception ex)
{
string a = ex.ToString();
}
return s;
}
public string Export_Excel97()
{
string s = "";
s = "<table border=\"1\">";
s += Worksheet97_Header();
s += Worksheet97_Data();
s += "</table>";
return s;
}
謝謝。
