我轉換數據表中使用下面的代碼,以擅長: 公共靜態無效ExportDataTabletoExcel(字符串文件名,數據表thetable) { 如果(thetable!= NULL ) {出口數據表到Excel,價值3E2成爲300,應該是文字3E2
//clear anything in io buffer
HttpContext.Current.Response.Clear();
//set to excel for to save file.
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.AddHeader(
"content-disposition", string.Format("attachment; filename={0}", fileName));
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.BufferOutput = true;
//write columns
string tab = "";
foreach (DataColumn dc in thetable.Columns)
{
HttpContext.Current.Response.Write(tab + dc.ColumnName);
tab = "\t";
}
HttpContext.Current.Response.Write("\n");
//write rows
int i;
foreach (DataRow dr in thetable.Rows)
{
tab = "";
for (i = 0; i < thetable.Columns.Count; i++)
{
//if (i != 1)
HttpContext.Current.Response.Write(tab + dr[i].ToString());
//else
//HttpContext.Current.Response.Write(tab + "'" + dr[i].ToString());
tab = "\t";
}
HttpContext.Current.Response.Write("\n");
}
HttpContext.Current.Response.End();
}
}
然而,對於值3E2或0E2或4E3,它被轉換爲數字..像1D2其它值被正確地轉換成字符串。
例如3E2成爲300等圍繞價值
您似乎正在使用'application/ms-excel' MIME類型提供製表符分隔的值文件。我懷疑這是不錯的做法。 – Thomas 2010-01-31 16:18:48
你能建議我應該用什麼來代替 – 2010-02-12 02:23:13
