求各位高手帮帮忙,最近在学c#开发ao,在模拟vb开发ao的代码中,遇到这样一段代码:<PRE><CODE>Public Sub</CODE> AddLayerFileToMap()
 <CODE>Dim</CODE> filePath <CODE>As String</CODE>
 filePath = "D:\arcgis\arcexe83\ArcObjects Developer Kit\samples\data\USA\states.lyr"
 <CODE>Dim</CODE> pGxLayer <CODE>As</CODE> IGxLayer
 <CODE>Dim</CODE> pGxFile <CODE>As</CODE> IGxFile

 <CODE>Set</CODE> pGxLayer = <CODE>New</CODE> GxLayer
 <CODE>Set</CODE> pGxFile = pGxLayer
 pGxFile.Path = filePath
 <CODE>Dim</CODE> pMxDoc <CODE>As</CODE> IMxDocument
 <CODE>Set</CODE> pMxDoc = ThisDocument
 pMxDoc.FocusMap.AddLayer pGxLayer.Layer
<CODE>End Sub</CODE>
其中Set pMxDoc = ThisDocument一句因为c#中没有ThisDocument这一类,又不知道怎样把它转换成c#语句,哪位高手帮帮忙,帮我把这一句改成c#语句,不甚感激!!!</PRE>
