通过

ContextAttributes.HighPriorityAttributes 属性

  • 项目

获取高优先级特性集合。

命名空间：  EnvDTE
程序集：  EnvDTE（在 EnvDTE.dll 中）

语法

声明
ReadOnly Property HighPriorityAttributes As ContextAttributes

ContextAttributes HighPriorityAttributes { get; }

property ContextAttributes^ HighPriorityAttributes {
    ContextAttributes^ get ();
}

abstract HighPriorityAttributes : ContextAttributes

function get HighPriorityAttributes () : ContextAttributes

属性值

类型：EnvDTE.ContextAttributes
一个 ContextAttributes 集合。

备注

此特性集合只有一个实例。 只能从 ContextAttributes 集合获得它。 如果 ContextAttributes 集合是针对窗口的，则 HighPriorityAttributes 不返回任何值。

这些特性总是有效的，它们的上下文包的优先级最高，从而使匹配主题居于它们各自目录的顶部。

示例

    Sub HighPriorityAttributesExample()
        Dim cas As EnvDTE.ContextAttributes
        Dim ca As EnvDTE.ContextAttribute

        Try
            cas = DTE.ContextAttributes
            ' List all regular and high priority attributes.
            ListAttr(ca, cas)
            ' Add a new F1 keyword to the global high priority 
            ' attributes collection.
            cas.HighPriorityAttributes.Add("NewAttribute", _
            "NewF1Keyword", vsContextAttributeType. _
            vsContextAttributeLookupF1)
            ListAttr(ca, cas)
            ' Remove the new high priority attribute.
            cas.HighPriorityAttributes.Item(1).Remove()
            ListAttr(ca, cas)
        Catch ex As System.Exception
            MsgBox("ERROR: " & ex.Message)
        End Try
    End Sub

    Function ListAttr(ByVal ca As ContextAttribute, ByVal cas As _
    ContextAttributes)
        Dim msg As String

        Try
            ' List regular attributes, their first value, and their count.
            For Each ca In cas
                msg = msg & ca.Name & "  " & ca.Values(0) & vbCr
            Next
            cas.Refresh()
            MsgBox("All Attributes: " & vbCr & msg & "Count: " & _
            cas.Count)

            ' List high-priority attributes, their first value, 
            ' and their count.
            msg = ""
            For Each ca In cas.HighPriorityAttributes
                msg = msg & ca.Name & "  " & ca.Values(0) & vbCr
            Next
            cas.Refresh()
            MsgBox("High-Priority Attributes: " & vbCr & msg & "Count: " _
            & cas.HighPriorityAttributes.Count)
        Catch ex As System.Exception
            MsgBox("ERROR: " & ex.Message)
        End Try
    End Function
