新建 导出 shape 文件

<P>请教一个问题：</P>
<P>新建shape文件，往里面写数据，并保存。</P>
<P> private IFeatureClass CreateFeatclass()<BR>        {<BR>            IFields pFields = new FieldsClass();<BR>            IFieldsEdit pFieldsEdit =  pFields as IFieldsEdit;<BR>            IGeometryDef pGeomDef = new GeometryDef();<BR>            IGeometryDefEdit pGeomDefEdit = pGeomDef as IGeometryDefEdit;<BR>            pGeomDefEdit.GeometryType_2 = esriGeometryType.esriGeometryPolyline;<BR>            pGeomDefEdit.HasM_2 = true;<BR>            pGeomDefEdit.HasZ_2 = true;</P>
<P>            IField pField = new FieldClass();<BR>            IFieldEdit pFieldEdit = pField as IFieldEdit;<BR>            pFieldEdit.Name_2 = "shape";<BR>            pFieldEdit.Type_2 = esriFieldType.esriFieldTypeGeometry;<BR>            pFieldEdit.GeometryDef_2 = pGeomDef;<BR>            pFieldsEdit.AddField(pField);</P>
<P>            return m_pFWs.CreateFeatureClass(m_newShapeName, pFields, null, null, esriFeatureType.esriFTSimple, "shape", "");<BR>        }</P>
<P>。。</P>
<P>   IWorkspaceEdit pWsEdit = m_pFWs as IWorkspaceEdit;<BR>             IFeatureClass pNewShapeFC = m_pFWs.OpenFeatureClass(m_newShapeName);</P>
<P>pWsEdit.StartEditOperation();</P>

<P>   IFeature pNewFeature = pNewShapeFC.CreateFeature();<BR>                pNewFeature.Shape = pNewPlyline;<BR>                pNewFeature.Store();                </P>
<P>。。</P>
<P>大体代码如上，.CreateFeature() 的时候报错，请高手指点。</P>
<P>谢谢<BR></P>

<P>出现什么错误？</P>
<P>请贴出错误提示</P>
