C#DataGridview 绑定与数据转化

1.DataGridView 绑定 list

var queryResult = db.Queryable<C_MODEL_DESC_T>().ToList();
dgv_data.DataSource = queryResult;
var pp= dgv_data.DataSource as List<C_MODEL_DESC_T>;

2.DataGridView 绑定 DataTable

DataTable dt = new DataTable();
dt = db.queryDataTable("C_MODEL_DESC_T");
dgv_data.DataSource = dt;
DataTable dt1 = dgv_data.DataSource as DataTable;
