C#DataSet的简便写法

//简写方法1实例化dataset
DataSet ds = new DataSet();
//实例化dataTable
DataTable dt = new DataTable(“Student”);
ds.Tables.Add(dt);
//定义表的结构
dt.Columns.Add(new DataColumn(“Sno”, Type.GetType(“System.Int32”)));
dt.Columns.Add(new DataColumn(“Sname”, Type.GetType(“System.String”)));
//为表赋值
dt.Rows.Add(new object[] { 95001, “张三” });
dt.Rows.Add(new object[] { 95002, “李四” });
//赋值
dataGridView2.DataSource = null;
dataGridView2.AutoGenerateColumns = false;
dataGridView2.DataSource = ds.Tables[“Student”];
