    myStrings[0] = "A";
    myStrings[1] = "String";
    myStrings[2] = "Array";
    TextBox1.DataBindings.Add("Text",myStrings,"");

    删除数据绑定

    Label1.DataBindings.Clear;

数据导航 CurrencyManager对象
    this.BindingContext[DataSet1.Customers];

    this.BindingContext[DataSet1.Customers].Position = 0;
    this.BindingContext[DataSet1.Customers].Position ++;
    this.BindingContext[DataSet1.Customers].Position --;
    this.BindingContext[DataSet1.Customers].Position = 4;  //第五条

数据绑定
ComboBox1.DataSource = DataSet1.Customers;
ComboBox1.DisplayMember = "CustomerID";

使用DataView
DataView myDataView = new DataView();
myDataView.Table = myDataTable;

排序
myDataView.Sort = "CustomerID";
myDataView.Sort = "State DESC, City";

筛选
myDataView.RowFilter = "City = 'Seattle'";
myDataView.RowFilter = "City IN ('Seattle','Tacoma','Blaine')";
myDataView.RowFilter = "City LIKE 'Se*t%e'";

DataViewManager
DataViewManager myDataViewManager = new DataViewManager(myDataSet);
DataViewManager myOtherDataViewManager = new DataViewManager();
myOtherDataViewManager.DataSet = myOtherDataSet;

myDataViewManager.DataViewSettings["Customers"].RowFilter = "State = 'WA'";
//获取
DataView myDataView = myDataViewManager.CreateDataView(DataSet1.Tables[0]);
