C#下拉绑定数据,带''全部''

/// <summary> /// 下拉绑定数据方法,带全部 /// </summary> /// <param name="dts">数据源</param> /// <param name="com">下拉框</param> public void ComBoxDT(DataTable dts, ComboBox com) { DataTable dt = dts; DataRow dr = dt.NewRow(); dr["ID"] = "0"; dr["Text"] = "全部"; dt.Rows.InsertAt(dr, 0); com.DataSource = dt; com.DisplayMember = "Text"; com.ValueMember = "ID"; } 据情况而论ID和Text,也可以写到参数里 public void ComBoxDT(DataTable dts, ComboBox com,string Text,string ID),这样大大增加了这个方法的灵活性
