示例

下面的代码示例声明三个DataBinding变量，dataBindingOutput2``dataBindingOutput1以及dataBindingOutput3用于访问对象的不同属性的myDataBinding2变量。 将 PropertyType 属性值分配给 dataBindingOutput2 字符串，并将其与字符串“属性类型为”连接，并将该值写入文件。

// Use the DataBindingCollection.GetEnumerator method
// to iterate through the myDataBindingCollection object
// and write the PropertyName, PropertyType, and Expression
// properties to a file for each DataBinding object
// in the MyDataBindingCollection object. 
myDataBindingCollection = DataBindings;
IEnumerator myEnumerator = myDataBindingCollection.GetEnumerator();

while (myEnumerator.MoveNext())
{
    myDataBinding2 = (DataBinding)myEnumerator.Current;
    String dataBindingOutput1, dataBindingOutput2, dataBindingOutput3;
    dataBindingOutput1 = String.Concat("The property name is ", myDataBinding2.PropertyName);
    dataBindingOutput2 = String.Concat("The property type is ", myDataBinding2.PropertyType.ToString(), "-", dataBindingOutput1);
    dataBindingOutput3 = String.Concat("The expression is ", myDataBinding2.Expression, "-", dataBindingOutput2);
    WriteToFile(dataBindingOutput3);

    myDataBindingExpression2 = String.Concat("<%#", myDataBinding2.Expression, "%>");
    myStringReplace2 = myDataBinding2.PropertyName.Replace(".", "-");
    myHtmlControlDesignBehavior.SetAttribute(myStringReplace2, myDataBindingExpression2);
    int index = myStringReplace2.IndexOf('-');
}// while loop ends

    ' Use the DataBindingCollection.GetEnumerator method
    ' to iterate through the myDataBindingCollection object
    ' and write the PropertyName, PropertyType, and Expression
    ' properties to a file for each DataBinding object
    ' in the MyDataBindingCollection object. 
    myDataBindingCollection = DataBindings
    Dim myEnumerator As IEnumerator = myDataBindingCollection.GetEnumerator()

    While myEnumerator.MoveNext()
        myDataBinding2 = CType(myEnumerator.Current, DataBinding)
        Dim dataBindingOutput1, dataBindingOutput2, dataBindingOutput3 As [String]
        dataBindingOutput1 = [String].Concat("The property name is ", myDataBinding2.PropertyName)
        dataBindingOutput2 = [String].Concat("The property type is ", myDataBinding2.PropertyType.ToString(), "-", dataBindingOutput1)
        dataBindingOutput3 = [String].Concat("The expression is ", myDataBinding2.Expression, "-", dataBindingOutput2)
        WriteToFile(dataBindingOutput3)

        myDataBindingExpression2 = [String].Concat("<%#", myDataBinding2.Expression, "%>")
        myStringReplace2 = myDataBinding2.PropertyName.Replace(".", "-")
        myHtmlControlDesignBehavior.SetAttribute(myStringReplace2, myDataBindingExpression2)
        Dim index As Integer = myStringReplace2.IndexOf("-"c)
    End While ' while loop ends
