         TimeFieldFormat

[Visual Basic]

Public Class TimeFieldFormat
Implements IDisposable

[C#]

public class TimeFieldFormat : IDisposable

备注

通过 FieldFormat 对象的 TimeFormat 属性，检索 TimeFieldFormat 对象。

示例

下面示例返回 TimeFieldFormat 对象。代码按名称获取 ReportObject，并将其转换为 FieldObject。如果字段是 TimeField，则方法将返回一个 TimeFieldFormat 对象。

  
[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;
      }
