.Dat文件到数据集

Question

我有一个.dat文件，我需要导入到数据表中。我使用.net框架4.5，它由〜分隔。我该如何导入？我试过了

string mySelectQuery = "SELECT * FROM " + fileName;
OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;DataSource=" + fileLocation + ";Extended Properties=\"text;HDR=YES;FMT=Delimited\"");
OleDbDataAdapter dsCmd = new OleDbDataAdapter(mySelectQuery, myConnection);
//Fill the DataSet object
dsCmd.Fill(myData, "Packets");

请帮忙
