返回被调用 EditPoint 对象的 AbsoluteCharOffset 的值是否小于给定 TextPoint 对象的值。
public:
bool LessThan(EnvDTE::TextPoint ^ Point);public:
bool LessThan(EnvDTE::TextPoint ^ Point);bool LessThan(EnvDTE::TextPoint const & Point);[System.Runtime.InteropServices.DispId(32)]
public bool LessThan (EnvDTE.TextPoint Point);[<System.Runtime.InteropServices.DispId(32)>]
abstract member LessThan : EnvDTE.TextPoint -> boolPublic Function LessThan (Point As TextPoint) As Boolean参数
返回
true 如果 Point 的 AbsoluteCharOffset 属性值大于调用点对象的 AbsoluteCharOffset 属性，则为; 否则为 false 。

注解
LessThan 如果与 ArgumentException Point 调用点对象不在同一文档中，则将引发。 对于 VirtualPoint 对象， LessThan 如果参数是，则比较虚拟位置 VirtualPoint 。 否则，会比较物理位置。
