我试图将一些XML数据转换为几何体并且出现错误。起初，我尝试获取特定的数字坐标并进行投射，但得到了类似的错误：
错误：（在代码中，因为它有标签）
A .NET Framework error occurred during execution of user-defined routine or aggregate "geometry":
System.FormatException: 24114: The label <boundary><MultiGeom in the input well-known text (WKT) is not valid. Valid labels are POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, GEOMETRYCOLLECTION, CIRCULARSTRING, COMPOUNDCURVE, CURVEPOLYGON and FULLGLOBE (geography Data Type only).
这是尝试CAST(MyColumn AS GEOMETRY)。
这就是XML数据的样子（注意 ... [values] ... 正在替换完整的坐标值，仅用于示例目的：

请注意，这些坐标对可以更多或相同（使用相同的XML）。
是否有表格可以转换此XML以使其与Geometry兼容？在查看Microsoft provides到几何数据类型时，我不会看到它应该出现的形式，而不是看起来像SHAPE和坐标，所以我＆＃39;我试图弄清楚他们如何使用我在上面的示例数据中提供的内容来推断他们所做的事情。
