创建DataTable与DataGridView进行绑定

private DataTable dt = new DataTable();

BindingSource bs = new BindingSource();

/// <summary>
/// 初始化DataTable
/// </summary>
public void InitDataTable()
{

//不允许自动生成，若改为允许，界面会自动增加DataTable列，那么界面上既会包含DataGridView中定义的列，也会包含DataTable定义的列
this.dataGridView1.AutoGenerateColumns = false;

DataColumn col = new DataColumn("No", typeof(int));
dt.Columns.Add(col);
dt.Columns.Add(new DataColumn("Addr", typeof(string)));
dt.Columns.Add(new DataColumn("FuntionType", typeof(string)));
dt.Columns.Add(new DataColumn("Result", typeof(string)));

bs.DataSource = dt;
this.dataGridView1.DataSource = bs;

//将DataGridView中的列与DataTable中的列进行数据绑定，this.cloNum为列名

this.colNum.DataPropertyName = "No";
this.colAddress.DataPropertyName = "Addr";
this.colFunction.DataPropertyName = "FuntionType";
this.colResult.DataPropertyName = "Result";
}
