推荐答案
Microsoft Jet OLE DB 4.0 TextFile连接字符串
< a href =http://www.connectionstrings.com/textfile/ =nofollow> TextFile连接字符串
Microsoft Jet OLE DB 4.0 TextFile Connection Strings TextFile Connect Strings
如果您要查看DataSet中的数据
if you want to view the data in a DataSet
string strFileName = textpath + "\\filename.csv";
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0; Data Source = " + System.IO.Path.GetDirectoryName(strFileName) +"; Extended Properties = \"Text;HDR=YES;FMT=Delimited\"");
conn.Open();
OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + System.IO.Path.GetFileName(strFileName), conn);
DataSet ds = new DataSet("Temp");
adapter.Fill(ds);
DataTable tb = ds.Tables[0];
