VisualBasicDesignerHelper.CreatePrecompiledVisualBasicValue 方法

定義

命名空間:

Microsoft.VisualBasic.Activities

組件:

System.Activities.dll

建立並回傳預先編譯好的 VisualBasicValue<TResult> 表達式。

此 API 支援此產品基礎結構，但無法直接用於程式碼之中。

Public Shared Function CreatePrecompiledVisualBasicValue (targetType As Type, expressionText As String, namespaces As IEnumerable(Of String), referencedAssemblies As IEnumerable(Of String), environment As LocationReferenceEnvironment, ByRef returnType As Type, ByRef compileError As SourceExpressionException, ByRef vbSettings As VisualBasicSettings) As Activity

參數

targetType

Type

那是預期中的表達類型。

expressionText

String

Visual Basic 語法中的表達式。

namespaces

IEnumerable<String>

匯入的命名空間。

referencedAssemblies

IEnumerable<String>

上述的組裝。

environment

LocationReferenceEnvironment

將名稱解析為其關聯 Argument 的 和 Variable 物件的機制。

returnType

Type

當此方法回傳時，包含表達式的結果型態。 這個參數會未初始化傳遞。

compileError

SourceExpressionException

當此方法回傳時，包含任何編譯錯誤，或 null 編譯是否成功。 這個參數會未初始化傳遞。 這個參數會未初始化傳遞。

vbSettings

VisualBasicSettings

當此方法回傳時，包含編譯表達式所需的設定。

傳回

Activity

預先編譯的 VisualBasicValue<TResult> 表達式。
