可讓您取得並設定報表中任何時間欄位的時間格式選項。

如需這個類型的成員清單，請參閱 TimeFieldFormat 成員。

System.Object
   CrystalDecisions.CrystalReports.Engine.EngineObjectBase
      CrystalDecisions.CrystalReports.Engine.ReportObjectProperty
         TimeFieldFormat

[Visual Basic]

Public Class TimeFieldFormat
   Implements IDisposable

[C#]

public class TimeFieldFormat : IDisposable

註解

透過 FieldFormat 物件的 TimeFormat 屬性來擷取 TimeFieldFormat 物件。

範例

下列範例會傳回 TimeFieldFormat 物件。程式碼會依名稱取得 ReportObject 並轉換為 FieldObject。如果欄位為 TimeField，則方法會傳回 TimeFieldFormat 物件。

[VJ#]

      private TimeFieldFormat getTimeFieldFormat
         (String reportObjectName)
      {
         FieldObject field;
         TimeFieldFormat timeFormat = null;
      
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
            if (field.get_DataSource().get_ValueType() == 
               FieldValueType.TimeField)
               timeFormat = field.get_FieldFormat().get_TimeFormat();
         }
         catch (Exception e)
         {
         }
         return timeFormat;
      }
      

[Visual Basic]

      Function GetTimeFieldFormat _
         (ByVal reportObjectName As String) As TimeFieldFormat
      
         Dim field As FieldObject
         Dim timeFormat As TimeFieldFormat
      
         If TypeOf _
            (Report.ReportDefinition.ReportObjects._
            Item(reportObjectName)) Is FieldObject Then
            field = _
               Report.ReportDefinition.ReportObjects._
               Item(reportObjectName)
            If field.DataSource.ValueType = _
               FieldValueType.TimeField Then
               timeFormat = field.FieldFormat.TimeFormat
               GetTimeFieldFormat = timeFormat
           Else : GetTimeFieldFormat = Nothing
           End If
         Else : GetTimeFieldFormat = Nothing
         End If
      End Function 
      

[C#]

      private TimeFieldFormat GetTimeFieldFormat
         (string reportObjectName)
      {
         FieldObject field;
         TimeFieldFormat timeFormat;
         field =
            Report.ReportDefinition.ReportObjects[reportObjectName]
            as FieldObject;
         if (field != null) 
         {
            if (field.DataSource.ValueType == 
               FieldValueType.TimeField)
            {
               timeFormat = field.FieldFormat.TimeFormat;
               return timeFormat;
            }
            else return null;
         }
         else return null;
      }
