我正在尝试在MapWinGIS控件中绘制多个多边形。绘图是“字典(int,字典(int,字典(字符串,浮点数)))”
上面的代码很好地填充了形状。我查看了Shape对象的“ IsValid”属性,这是事实。但是,当我运行代码以将形状对象添加到shapefile obj时,它不会添加。 shapefile对象的属性“ numShapes”为零。请帮助确定我在做什么错。到目前为止没有错误。只是一个空白的地图。
最佳答案
将CreateNew (string ShapefileName, ShpfileType ShapefileType)
函数更改为CreateNewWithShapeID (string ShapefileName, ShpfileType ShapefileType)
关于c# - mapwingis形状未添加到shapefile,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/26962239/
