可讓您取得並設定布林欄位的布林輸出型別。

如需這個類型所有成員的清單，請參閱 BooleanFieldFormat 成員。

Object

   BooleanFieldFormat

[Visual Basic]

Public Class BooleanFieldFormat

[C#]

public class BooleanFieldFormat

[C++]

__gc public class BooleanFieldFormat

[VJ#]

public class BooleanFieldFormat

註解

透過 FieldFormat 物件的 BooleanFormat 屬性來擷取 BooleanFieldFormat 物件。

範例

下列範例會傳回 BooleanFieldObject 物件。

[Visual Basic]

Function GetBooleanFieldformat _
(ByVal reportObjectName As String) As BooleanFieldFormat
   Dim field As FieldObject
   Dim booleanFormat As BooleanFieldFormat

   ' 依名稱取得 ReportObject 並將其轉換為 FieldObject。
   If TypeOf _
   (Report.ReportDefinition.ReportObjects. _
   Item(reportObjectName)) Is FieldObject Then
      field = _
      Report.ReportDefinition.ReportObjects. _
      Item(reportObjectName)
     ' 檢查欄位是否為 BooleanField，取得 
     '  BooleanFieldFormat 物件，然後將它傳回來。
     If field.DataSource.ValueType = _
     FieldValueType.BooleanField Then
        booleanFormat = field.FieldFormat.BooleanFormat
        GetBooleanFieldformat = booleanFormat
     Else : GetBooleanFieldformat = Nothing
     End If
   Else : GetBooleanFieldformat = Nothing
   End If
End Function
