名稱	Description
CanExport(ICollection<Assembly>)	會取得一個值，指示是否能匯出一組組合語言中的 .common language runtime（CLR）型別集合。
CanExport(ICollection<Type>)	會取得一個值，指示是否能匯出包含在 a ICollection<T> 中的 .common language runtime（CLR）型別集合。
CanExport(Type)	會取得一個值，指示是否可以匯出指定的通用語言執行時（CLR）型態。

備註

並非所有 CLR 類型都能用於資料合約。欲了解更多可序列化的資訊，請參閱資料合約序列化器支援的類型。

範例

以下範例在呼叫CanExport(Type)方法之前，先呼叫該Export(Type)方法。

static void ExportXSD()
{
    XsdDataContractExporter exporter = new XsdDataContractExporter();
    if (exporter.CanExport(typeof(Employee)))
    {
        exporter.Export(typeof(Employee));
        Console.WriteLine("number of schemas: {0}", exporter.Schemas.Count);
        Console.WriteLine();
        XmlSchemaSet mySchemas = exporter.Schemas;

        XmlQualifiedName XmlNameValue = exporter.GetRootElementName(typeof(Employee));
        string EmployeeNameSpace = XmlNameValue.Namespace;

        foreach (XmlSchema schema in mySchemas.Schemas(EmployeeNameSpace))
        {
            schema.Write(Console.Out);
        }
    }
}

Shared Sub ExportXSD() 

    Dim exporter As New XsdDataContractExporter()

    ' Use the ExportOptions to add the Possessions type to the 
    ' collection of KnownTypes. 
    Dim eOptions As New ExportOptions()
    eOptions.KnownTypes.Add(GetType(Possessions))        
    exporter.Options = eOptions

    If exporter.CanExport(GetType(Employee)) Then
        exporter.Export(GetType(Employee))
        Console.WriteLine("number of schemas: {0}", exporter.Schemas.Count)
        Console.WriteLine()
        Dim mySchemas As XmlSchemaSet = exporter.Schemas
        
        Dim XmlNameValue As XmlQualifiedName = _
           exporter.GetRootElementName(GetType(Employee))
        Dim EmployeeNameSpace As String = XmlNameValue.Namespace
        
        Dim schema As XmlSchema
        For Each schema In  mySchemas.Schemas(EmployeeNameSpace)
            schema.Write(Console.Out)
        Next schema
    End If

End Sub
