TransformerInfo 类

定义

指定一个自定义类,该类扩展供 Web 部件连接使用的 WebPartTransformer 类。Specifies a custom class that extends the WebPartTransformer class for use by Web Part connections.

public ref class TransformerInfo sealed : System::Configuration::ConfigurationElement
public sealed class TransformerInfo : System.Configuration.ConfigurationElement
type TransformerInfo = class
    inherit ConfigurationElement
Public NotInheritable Class TransformerInfo
Inherits ConfigurationElement
继承
TransformerInfo

示例

下面的配置文件节选显示了如何以声明方式为TransformerInfo类的几个属性指定值。The following configuration file excerpt shows how to declaratively specify values for several properties of the TransformerInfo class.

<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>  

下面的代码示例演示如何使用 TransformerInfo 类。The following code example shows how to use the TransformerInfo class. 此代码示例是为WebPartsSection类提供的更大示例的一部分。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();

' 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()

注解

TransformerInfo对象指定扩展WebPartTransformer类的自定义类。TransformerInfo objects specify custom classes that extend the WebPartTransformer class. 这些自定义转换器类作为 Web 部件之间的桥梁, 在具有不兼容连接点的 Web 部件之间转换数据。These custom transformer classes act as bridges between Web Parts, translating data between Web Parts with incompatible connection points.
