您可以这样做是在Excel中打开CSV,在SQL MS中打开要添加的表,然后只需复制和粘贴。只要列数相同就应该工作。

您需要获取数据,在字符串中创建逗号分隔列表,然后将其流式传输到用户浏览器。
StringBuilder sw = new StringBuilder();
//assuming you have a datatable named dt
int NumColumns = dt.Columns.Count;
for (int i = 0; i < NumColumns; i++)
{
sw.Write(dt.Columns[i]);
if (i < dt.Columns.Count - 1)
{
sw.Write(",");
}
}
sw.Write(sw.NewLine);
// write = the rows.
foreach (DataRow dr in dt.Rows)
{
for (int i = 0; i < NumColumns; i++)
{
sw.Write(dr[i].ToString());
if (i < NumColumns - 1)
{
sw.Write(",");
}
}
sw.Write(sw.NewLine);
}
