[原创]求助c#与AO开发
<P>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:</P><PRE><CODE><FONT color=#0000ff>Public Sub</FONT></CODE> AddLayerFileToMap()
<CODE><FONT color=#0000ff>Dim</FONT></CODE> filePath <CODE><FONT color=#0000ff>As String</FONT></CODE> filePath = "D:\arcgis\arcexe83\ArcObjects Developer Kit\samples\data\USA\states.lyr" <CODE><FONT color=#0000ff>Dim</FONT></CODE> pGxLayer <CODE><FONT color=#0000ff>As</FONT></CODE> IGxLayer <CODE><FONT color=#0000ff>Dim</FONT></CODE> pGxFile <CODE><FONT color=#0000ff>As</FONT></CODE> IGxFile <CODE><FONT color=#0000ff>Set</FONT></CODE> pGxLayer = <CODE><FONT color=#0000ff>New</FONT></CODE> GxLayer <CODE><FONT color=#0000ff>Set</FONT></CODE> pGxFile = pGxLayer pGxFile.Path = filePath <CODE><FONT color=#0000ff>Dim</FONT></CODE> pMxDoc <CODE><FONT color=#0000ff>As</FONT></CODE> IMxDocument <CODE><FONT color=#0000ff>Set</FONT></CODE> pMxDoc = ThisDocument pMxDoc.FocusMap.AddLayer pGxLayer.Layer <CODE><FONT color=#0000ff>End Sub</FONT></CODE> 其中<FONT color=#0000ff>Set</FONT> 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> |
