member this.CanImport : System.Xml.Schema.XmlSchemaSet -> bool

member this.CanImport : System.Xml.Schema.XmlSchemaSet -> bool

Public Function CanImport (schemas As XmlSchemaSet) As Boolean

參數

schemas: XmlSchemaSet

XmlSchemaSet包含可轉換的模式。

傳回

Boolean

true若結構可轉換為資料合約型態;否則，。 false

ArgumentNullException

參數 schemas 為 null。

InvalidDataContractException

匯入過程中涉及的資料合約無效。

範例

以下範例將呼叫該CanImport方法來判斷是否能生成。CodeCompileUnit

static CodeCompileUnit Import(XmlSchemaSet schemas)
{

    XsdDataContractImporter imp = new XsdDataContractImporter();

    // The EnableDataBinding option adds a RaisePropertyChanged method to
    // the generated code. The GenerateInternal causes code access to be
    // set to internal.
    ImportOptions iOptions = new ImportOptions();
    iOptions.EnableDataBinding = true;
    iOptions.GenerateInternal = true;
    imp.Options = iOptions;

    if (imp.CanImport(schemas))
    {
        imp.Import(schemas);
        return imp.CodeCompileUnit;
    }
    else
    {
        return null;
    }
}

Shared Function Import(ByVal schemas As XmlSchemaSet) As CodeCompileUnit 

    Dim imp As New XsdDataContractImporter()
   ' The EnableDataBinding option adds a RaisePropertyChanged method to
   ' the generated code. The GenerateInternal causes code access to be
   ' set to internal.
   Dim iOptions As New ImportOptions()
   iOptions.EnableDataBinding = true
   iOptions.GenerateInternal = true
   imp.Options = IOptions

    If imp.CanImport(schemas) Then
        imp.Import(schemas)
        Return imp.CodeCompileUnit
    Else
        Return Nothing
    End If
End Function
