The TransformerInfoCollection class allows you to programmatically access and modify the transformers section of the webParts section of a configuration file.

TransformerInfo objects, as part of a TransformerInfoCollection, specify custom classes that extend the WebPartTransformer class. These transformer classes act as bridges between connected Web Parts, translating data sent by a connection provider into something that the connection consumer can accept.

The following configuration file excerpt shows how to declaratively specify values for several properties of the TransformerInfoCollection class.

<system.web>
  <webParts>
    <transformers>
      <clear />
      <remove name="RowToKeysTransformer" />
      <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>

The following code example shows how to use the TransformerInfoCollection class. This code example is part of a larger example provided for the WebPartsSection class.

// 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();
