Example

[Visual Basic, C#, C++] In the following code example the DataBinding output is generated using this Concat method.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Concat. For other examples that might be available, see the individual overload topics.

[Visual Basic] 
myDataBindingCollection = DataBindings
myEnumerator = 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, True)
   Dim index As Integer = myStringReplace2.IndexOf("-"c)
End While ' while loop ends

[C#] 
myDataBindingCollection = DataBindings;
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,true);
   int index = myStringReplace2.IndexOf('-');
}// while loop ends

[C++] 
myDataBindingCollection = DataBindings;
myEnumerator = myDataBindingCollection->GetEnumerator();
while(myEnumerator->MoveNext())
{

    myDataBinding2 = dynamic_cast<DataBinding*>(myEnumerator->Current);
    String* dataBindingOutput1;
    String* dataBindingOutput2;
    String* dataBindingOutput3;

    dataBindingOutput1=String::Concat(S"The property name is ", myDataBinding2->PropertyName);
    dataBindingOutput2=String::Concat(S"The property type is ", myDataBinding2->PropertyType->ToString(), S"-",dataBindingOutput1);
    dataBindingOutput3=String::Concat(S"The expression is ", myDataBinding2->Expression,S"-", dataBindingOutput2);
    WriteToFile(dataBindingOutput3);
    myDataBindingExpression2 = String::Concat(S"<%#", myDataBinding2->Expression,S"%>");
    myStringReplace2 = myDataBinding2->PropertyName->Replace(S".",S"-");
    myHtmlControlDesignBehavior->SetAttribute(myStringReplace2, myDataBindingExpression2, true);
    int index = myStringReplace2->IndexOf('-');
}// while loop ends
