重要

一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。

返回一个值，该值指示给定点对象的 AbsoluteCharOffset 值是否等于调用 EditPoint 对象的值。

public:
 bool EqualTo(EnvDTE::TextPoint ^ Point);

public:
 bool EqualTo(EnvDTE::TextPoint ^ Point);

bool EqualTo(EnvDTE::TextPoint const & Point);

[System.Runtime.InteropServices.DispId(31)]
public bool EqualTo (EnvDTE.TextPoint Point);

[<System.Runtime.InteropServices.DispId(31)>]
abstract member EqualTo : EnvDTE.TextPoint -> bool

Public Function EqualTo (Point As TextPoint) As Boolean

参数

Point: TextPoint

必需。要与调用 TextPoint 点对象进行比较的 EditPoint 对象。

Boolean

如果 Point 与调用 AbsoluteCharOffset 点对象具有相同的 EditPoint 属性值，则返回 true；否则返回 false。

实现

EqualTo(TextPoint)

属性: DispIdAttribute

    ' Create a new text file.

    for (int i = 1; i <= 10; i++)  
        point1.Insert("Line " + i.ToString() + "\r\n");  

    // Create an edit point at the text document's StartPoint and   
    // EndPoint; CompareEditPoints displays "point1 comes before   
    // point2."  
    point1 = txtDoc.StartPoint.CreateEditPoint();  
    point2 = txtDoc.EndPoint.CreateEditPoint();  
    CompareEditPoints(point1, point2);  
}  

public void CompareEditPoints(EditPoint point1, EditPoint point2)  
{  
    if (point1.LessThan(point2))  
        MessageBox.Show("point1 comes before point2.");  
    else if (point1.GreaterThan(point2))  
        MessageBox.Show("point2 comes before point1.");  
    else if (point1.EqualTo(point2))  
        MessageBox.Show("point1 and point2 occupy the same location.");  
}

注解

EqualTo 如果与 ArgumentException Point 调用点对象不在同一文档中，则会引发异常。对于 VirtualPoint ， EqualTo 如果参数是，则比较虚拟位置 VirtualPoint 。否则，它将比较 "物理" 位置。
