方法1：用一个System.Web.UI.HtmlControls.HtmlInputFile去handle文件选取
以下是button click event中的code，用来执行当文件选取了之后读取文件的内容
System.Web.HttpPostedFile input = Request.Files[0]; if (input != null && input.ContentLength != 0)
{
string path = input.FileName.ToString();
System.IO.StreamReader reader = new System.IO.StreamReader(path); reader.Peek();
while (reader.Peek() > 0)
{
string str = reader.ReadLine();
string[] split = str.Split(',');
if (split[0] != "" && split[1] != "")
{
System.Data.DataSet ds = new DataSet();
System.Data.DataRow dr = ds.Tables[0].NewRow();
dr[0] = split[0];
dr[1] = split[1];
ds.Tables[0].Rows.Add(dr);
}
}
}
方法2：当成SQL的数据表来读取
SELECT * INTO theImportTable
FROM
OPENROWSET('MSDASQL',
'Driver={Microsoft Text Driver (*.txt; *.csv)};DEFAULTDIR=D:;Extensions=CSV;',
'SELECT * FROM CSVFile.csv')
方法3：文件当做一个数据库读取，使用Ole驱动
int intColCount = 0;
DataTable mydt = new DataTable("myTableName"); DataColumn mydc;
DataRow mydr; string strpath = "";
string strline;
string[] aryline; System.IO.StreamReader mysr = new System.IO.StreamReader(strpath); while ((strline = mysr.ReadLine()) != null)
{
aryline = strline.Split(new char[] { '|' }); intColCount = aryline.Length;
for (int i = 0; i < aryline.Length; i++)
{
mydc = new DataColumn(aryline[i]);
mydt.Columns.Add(mydc);
} mydr = mydt.NewRow();
for (int i = 0; i < intColCount; i++)
{
mydr[i] = aryline[i];
}
mydt.Rows.Add(mydr);
}
