SoapServices.GetInteropFieldTypeAndNameFromXmlAttribute 方法

定義

命名空間:

System.Runtime.Remoting

組件:

mscorlib.dll

從 XML 屬性名稱、命名空間和包含物件的 Type，擷取欄位型別。

public:
 static void GetInteropFieldTypeAndNameFromXmlAttribute(Type ^ containingType, System::String ^ xmlAttribute, System::String ^ xmlNamespace, [Runtime::InteropServices::Out] Type ^ % type, [Runtime::InteropServices::Out] System::String ^ % name);

public static void GetInteropFieldTypeAndNameFromXmlAttribute (Type containingType, string xmlAttribute, string xmlNamespace, out Type type, out string name);

static member GetInteropFieldTypeAndNameFromXmlAttribute : Type * string * string * Type * string -> unit

Public Shared Sub GetInteropFieldTypeAndNameFromXmlAttribute (containingType As Type, xmlAttribute As String, xmlNamespace As String, ByRef type As Type, ByRef name As String)

參數

containingType

Type

物件的 Type，其中含有欄位。

xmlAttribute

String

欄位型別的 XML 屬性名稱。

xmlNamespace

String

欄位型別的 XML 命名空間。

type

Type

當這個方法傳回時，含有欄位的 Type。 這個參數會以未初始化的狀態傳遞。

name

String

當這個方法傳回時，含有存有欄位名稱的 String。 這個參數會以未初始化的狀態傳遞。

例外狀況

SecurityException

立即呼叫端沒有基礎結構使用權限。

範例

下列程式碼範例會顯示如何使用這個方法。 此程式代碼範例是提供給 類別之較大範例的 SoapServices 一部分。

// Get the name and the type of the field using its XML
// element name and its XML namespace. For this query to work,
// the containing type must be preloaded, and the XML element
// name and the XML namespace must be explicitly declared on
// the field using a SoapFieldAttribute.
// Preload the containing type.
SoapServices::PreLoad( ExampleNamespace::ExampleClass::typeid );

// Get the name and the type of a field that will be
// serialized as an XML element.
Type^ containingType = ExampleNamespace::ExampleClass::typeid;
String^ xmlElementNamespace = L"http://example.org/ExampleFieldNamespace";
String^ xmlElementName = L"ExampleFieldElementName";
Type^ fieldType;
String^ fieldName;
SoapServices::GetInteropFieldTypeAndNameFromXmlElement(
   containingType,xmlElementName,xmlElementNamespace,fieldType,fieldName );
Console::WriteLine( L"The type of the field is {0}.", fieldType );
Console::WriteLine( L"The name of the field is {0}.", fieldName );

// Get the name and the type of a field that will be
// serialized as an XML attribute.
String^ xmlAttributeNamespace =
   L"http://example.org/ExampleAttributeNamespace";
String^ xmlAttributeName = L"ExampleFieldAttributeName";
SoapServices::GetInteropFieldTypeAndNameFromXmlAttribute(
   containingType,xmlAttributeName,xmlAttributeNamespace,fieldType,fieldName );
Console::WriteLine( L"The type of the field is {0}.", fieldType );
Console::WriteLine( L"The name of the field is {0}.", fieldName );

// Get the name and the type of the field using its XML 
// element name and its XML namespace. For this query to work,
// the containing type must be preloaded, and the XML element 
// name and the XML namespace must be explicitly declared on 
// the field using a SoapFieldAttribute.

// Preload the containing type.
SoapServices.PreLoad(typeof(ExampleNamespace.ExampleClass));

// Get the name and the type of a field that will be 
// serialized as an XML element.
Type containingType = typeof(ExampleNamespace.ExampleClass);
string xmlElementNamespace = 
    "http://example.org/ExampleFieldNamespace";
string xmlElementName = "ExampleFieldElementName";
Type fieldType;
string fieldName;
SoapServices.GetInteropFieldTypeAndNameFromXmlElement(
    containingType, xmlElementName, xmlElementNamespace, 
    out fieldType, out fieldName);
Console.WriteLine(
    "The type of the field is {0}.",
    fieldType);
Console.WriteLine(
    "The name of the field is {0}.",
    fieldName);

// Get the name and the type of a field that will be 
// serialized as an XML attribute.
string xmlAttributeNamespace = 
    "http://example.org/ExampleAttributeNamespace";
string xmlAttributeName = "ExampleFieldAttributeName";
SoapServices.GetInteropFieldTypeAndNameFromXmlAttribute(
    containingType, xmlAttributeName, xmlAttributeNamespace, 
    out fieldType, out fieldName);
Console.WriteLine(
    "The type of the field is {0}.",
    fieldType);
Console.WriteLine(
    "The name of the field is {0}.",
    fieldName);

備註

假設包含對象的類型以及 .NET Framework 所讀取的 XML 屬性和 XML 命名空間，目前的方法會傳回實際的 Common Language Runtime 功能變數名稱和欄位類型。 然後，.NET Framework 會使用此資訊，以從 XML 數據流讀取的數據填入該欄位。
