定义

命名空间:
System.Windows.Documents.Serialization
程序集:
PresentationFramework.dll

为将使用指定描述符的指定SerializerWriter初始化派生自抽象Stream类的对象。

public:
 System::Windows::Documents::Serialization::SerializerWriter ^ CreateSerializerWriter(System::Windows::Documents::Serialization::SerializerDescriptor ^ serializerDescriptor, System::IO::Stream ^ stream);
public System.Windows.Documents.Serialization.SerializerWriter CreateSerializerWriter(System.Windows.Documents.Serialization.SerializerDescriptor serializerDescriptor, System.IO.Stream stream);
member this.CreateSerializerWriter : System.Windows.Documents.Serialization.SerializerDescriptor * System.IO.Stream -> System.Windows.Documents.Serialization.SerializerWriter
Public Function CreateSerializerWriter (serializerDescriptor As SerializerDescriptor, stream As Stream) As SerializerWriter

参数

serializerDescriptor
SerializerDescriptor

一个包含 SerializerDescriptor 的 SerializerWriter序列化信息。

stream
Stream

Stream返回的对象写入到的对象。

返回

SerializerWriter

派生自 SerializerWriter的类的对象。

例外

ArgumentNullException

其中一个参数为 null。

ArgumentException

指定 serializerDescriptor 了错误的版本。

-或-

它未注册。

-或-

找不到程序集文件。

-或-

无法加载程序集。

示例

以下示例演示如何返回 CreateSerializerWriter 用于保存文件的插件序列化编写器。

// Create a SerializerProvider for accessing plug-in serializers.
SerializerProvider serializerProvider = new SerializerProvider();

// Locate the serializer that matches the fileName extension.
SerializerDescriptor selectedPlugIn = null;
foreach ( SerializerDescriptor serializerDescriptor in
                serializerProvider.InstalledSerializers )
{
    if ( serializerDescriptor.IsLoadable &&
         fileName.EndsWith(serializerDescriptor.DefaultFileExtension) )
    {   // The plug-in serializer and fileName extensions match.
        selectedPlugIn = serializerDescriptor;
        break; // foreach
    }
}

// If a match for a plug-in serializer was found,
// use it to output and store the document.
if (selectedPlugIn != null)
{
    Stream package = File.Create(fileName);
    SerializerWriter serializerWriter =
        serializerProvider.CreateSerializerWriter(selectedPlugIn,
                                                  package);
    IDocumentPaginatorSource idoc =
        flowDocument as IDocumentPaginatorSource;
    serializerWriter.Write(idoc.DocumentPaginator, null);
    package.Close();
    return true;
}

注解

只有完全受信任的应用程序才能调用 CreateSerializerWriter。
