谢谢,

公共属性字段(ByVal strFieldName As String,可选ByVal tableName As String ="",可选ByVal rowNum As Integer = 0)
获取
如果tableName <> ""然后返回objDataSet.Tables(tableName).Rows(rowNum)(strField Name)
返回objDataSet.Tables(objDataSet.Tables.Count - 1).Rows(rowNum)(strFieldName)
结束获取
套装(ByVal价值)
如果tableName<> ""然后
objDataSet.Tables(tableName).Rows(rowNum)(strField Name)= Value
Else
objDataSet.Tables(objDataSet.Tables) .Count - 1).Rows(rowNum)(strFieldName)= Value
结束如果
结束集
结束财产
Hi,
In vb.Net one can pass arguments to properties. How does one achieve it in c#? Given below is the vb.net code for passing arguments to property getters and setters..
Thanks,
Prachi
Public Property Field(ByVal strFieldName As String, Optional ByVal tableName As String = "", Optional ByVal rowNum As Integer = 0)
Get
If tableName <> "" Then Return objDataSet.Tables(tableName).Rows(rowNum)(strField Name)
Return objDataSet.Tables(objDataSet.Tables.Count - 1).Rows(rowNum)(strFieldName)
End Get
Set(ByVal Value)
If tableName <> "" Then
objDataSet.Tables(tableName).Rows(rowNum)(strField Name) = Value
Else
objDataSet.Tables(objDataSet.Tables.Count - 1).Rows(rowNum)(strFieldName) = Value
End If
End Set
End Property

在C#中,你只能将参数传递给被调用的特殊属性
索引器。你需要让你的房产成为你班级的索引。

In C#, you can only pass parameters to special properties called
indexers. You''ll need to make your property an indexer for your class.

我认为C#对于这个索引器来说非常麻烦。我想知道为什么
Hejlsberg等人决定采用这种复杂性,当Delphi以VB.NET的方式运行参数化属性。他们坚持
已经知道更好....

I think C# is quite cumbersome with this indexer-thingy. I wonder why
Hejlsberg et al decided do go for such complexity, when Delphi sported
parameterized properties in just the way VB.NET does stuff. They shoulod
have known better....

这就是为什么Delphi 2005提供的Delphi for .NET(以及C#)是
这么好的主意。 Delphi在最佳OO框架.NET中的所有遗产。

Which is why Delphi for .NET as provided (along with C#) by Delphi 2005 is
such a good idea. All the heritage of Delphi in the best OO framework .NET.
