将Excel导入DataGridView 中的"select * from [Sheet1$]"中[ ]里面表单名的动态获取

Sheet1$是Excel默认的第一个表名，如果改动：select * from [Sheet1$]"将查询失败，因此应根据选择自动获取excel表名：

 OpenFileDialog ofd = new OpenFileDialog();  //选择文件路径
     ofd.Title = "Excel文件";
     ofd.FileName = "";
     ofd.Filter = "Excel文件(*.xls)| *.xls";
 string Path = ofd.FileName;
 string tableName = "";

 string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Path + ";" + "Extended Properties=Excel 8.0;";
 OleDbConnection conn = new OleDbConnection(strConn);
 conn.Open();
 System.Data.DataTable sTable = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
 tableName = sTable.Rows[][].ToString().Trim();

 for (int i = ; i < sTable.Rows.Count; i++)
 {
     schemaTable.Rows[i][].ToString().TrimStart('\'').Trim('\'', '$');
 }

 string strExcel = "select * from [" + tableName + "]";
 OleDbDataAdapter myCommand = new OleDbDataAdapter(strExcel, strConn);
 DataSet ds = new DataSet();
 DataTable table1 = new DataTable();
 myCommand.Fill(table1);
 //==========最后绑定
 dataGridView1.DataSource = table1;
