地狱克雷格,
感谢您的快速答复。 从来就遇到了一组很奇怪的行为。 例如。 所提到的线串不能被读入一个地理类型,但它的工作原理采用几何类型。 然而,我可以选择生成的几何对象,并且可以在管理工作室内的空间结果标签查看它。 如果我叫.STNumPoints此几何对象,我得到下面的异常()方法:
24144: This operation cannot be completed because the instance is not valid
如果我打电话STNumPoints(在此之前几何对象上调用MakeValid()),一切工作正常。 不需要MakeValid只选择几何尺寸和显示。
相同的数据不能被读入一个地理类型。 如果最后的坐标点被删除它就像魅力。
我试图执行该样本数据是:

这不恕我直言不能超过单个半球。 It's甚至没有一个大的区域。
设置@g的几何形状,并呼吁与几何形状,而不是goegraphy的STGeomFromText静态方法,你不叫喜欢STNumPoints()或STDistance()它的方法可以作为长。
这是变得非常混乱...

即该线串失败,24(!!!!)点,并与23作品如果任何人有一个想法是什么问题可能是... i'm变得有些沮丧。 附近的太多点将一直在为第一线串的理由,但我就是不能相信,24点过于接近,彼此可能会导致这个错误。
