O excerto seguinte do ficheiro de configuração mostra como especificar declarativamente valores para várias propriedades da TransformerInfo classe.

<system.web>
  <webParts>
    <transformers>
      <add name="RowToFieldTransformer"
        type="System.Web.UI.WebControls.WebParts.RowToFieldTransformer" />
      <add name="RowToFilterTransformer"
        type="System.Web.UI.WebControls.WebParts.RowToFilterTransformer" />
      <add name="RowToParametersTransformer"
        type="System.Web.UI.WebControls.WebParts.RowToParametersTransformer" />
    </transformers>
  </webParts>
</system.web>

O exemplo de código seguinte mostra como usar a TransformerInfo classe. Este exemplo de código faz parte de um exemplo maior fornecido para a WebPartsSection classe.

// Add a Transfomer Info Object to the collection using a constructor.
webPartsSection.Transformers.Add(new TransformerInfo(
    "RowToFilterTransformer",
    "MyCustomTransformers.RowToFilterTransformer"));

// Show all TransformerInfo objects in the collection.
for (int ti = 0;
    ti < webPartsSection.Personalization.Providers.Count; ti++)
{
    Console.WriteLine("  #{0} Name={1} Type={2}", ti,
        webPartsSection.Transformers[ti].Name,
        webPartsSection.Transformers[ti].Type);
}

// Remove a TransformerInfo object by name.
webPartsSection.Transformers.Remove("RowToFilterTransformer");

// Remove a TransformerInfo object by index.
webPartsSection.Transformers.RemoveAt(0);

// Clear all TransformerInfo objects from the collection.
webPartsSection.Transformers.Clear();

' Add a Transfomer Info Object to the collection using a constructor.
webPartsSection.Transformers.Add(New TransformerInfo( _
  "RowToFilterTransformer", _
  "MyCustomTransformers.RowToFilterTransformer"))

' Show all TransformerInfo objects in the collection.
Dim ti As Integer
For ti = 0 To webPartsSection.Personalization.Providers.Count - 1
  Console.WriteLine("  #{0} Name={1} Type={2}", ti, _
    webPartsSection.Transformers(ti).Name, _
    webPartsSection.Transformers(ti).Type)
Next

' Remove a TransformerInfo object by name.
webPartsSection.Transformers.Remove("RowToFilterTransformer")

' Remove a TransformerInfo object by index.
webPartsSection.Transformers.RemoveAt(0)

' Clear all TransformerInfo objects from the collection.
webPartsSection.Transformers.Clear()

Observações

TransformerInfo os objetos especificam classes personalizadas que estendem a WebPartTransformer classe. Estas classes personalizadas de transformador funcionam como pontes entre Web Parts, traduzindo dados entre Web Parts com pontos de ligação incompatíveis.
