将CSV读入使用OLEDB

Question

当我尝试使用OLEDB连接字符串读取csv文件时,我收到错误"找不到可安装的ISAM".

请协助

我的代码是:

       if (File .Exists(openFileDialog1 .FileName ))
       {
        ConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data          Source="+openFileDialog1.FileName +";Extended Properties=text;HDR=Yes;FMT=Delimited");
        Con = new OleDbConnection(ConnectionString);
        string query = "Select * From [Sheet1$]";
        Con.Open();
        DataAdapter = new OleDbDataAdapter(query, Con);
        dt = new DataTable(); 
        DataAdapter.Fill(dt);

        dataGridView1.DataSource = dt;
       }

"当连接字符串的语法不正确时,也会生成此错误." - msdn

当我试图复制你的连接字符串时,似乎很喜欢那里有很多空格.

 ConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;DataSource="+openFileDialog1.FileName +";Extended Properties=text;HDR=Yes;FMT=Delimited");
