定义

命名空间:

EnvDTE80

程序集:

EnvDTE80.dll

程序集:

获取一个值，该值指示是否 CodeType 可以从对象获取对象 CodeImport 。

public:
 property bool IsCodeType { bool get(); };

public:
 property bool IsCodeType { bool get(); };

[System.Runtime.InteropServices.DispId(6)]
public bool IsCodeType { [System.Runtime.InteropServices.DispId(6)] [System.Runtime.InteropServices.TypeLibFunc(1024)] get; }

[<System.Runtime.InteropServices.DispId(6)>]
[<get: System.Runtime.InteropServices.DispId(6)>]
[<get: System.Runtime.InteropServices.TypeLibFunc(1024)>]
member this.IsCodeType : bool

Public ReadOnly Property IsCodeType As Boolean

属性值

Boolean

一个布尔值， true 如果 CodeType 对象可从对象获取，则该值为 CodeImport ; 否则为 false 。

实现

IsCodeType

属性

DispIdAttribute TypeLibFuncAttribute

示例

Sub IsCodeTypeExample(ByVal dte As DTE2)  
    ' NOTE: This example requires a reference to the System.Text   
    '       namespace.  
    ' Before running this example, open a code document from a project.  
    Dim item As ProjectItem = dte.ActiveDocument.ProjectItem  
    Dim sb As New StringBuilder  

    RecurseElements(item.FileCodeModel.CodeElements, 0, sb)  

    MsgBox(item.Name & " contains the following elements:" & vbCrLf & _  
        vbCrLf & sb.ToString())  

End Sub  

Sub RecurseElements(ByVal elems As CodeElements, _  
    ByVal level As Integer, ByVal sb As StringBuilder)  

    Dim elem As CodeElement  
    For Each elem In elems  
        ' Add element to the list of names.  
        sb.Append(" "c, level * 8)  
        sb.Append(elem.Name & " [" & elem.Kind.ToString() & "]" & _  
            vbCrLf)  

        ' Call this function recursively if element has children.  
        If elem.Kind = vsCMElement.vsCMElementNamespace Then  
            RecurseElements(CType(elem, CodeNamespace).Members, _  
                level + 1, sb)  
        ElseIf elem.IsCodeType Then  
            RecurseElements(CType(elem, CodeType).Members, _  
                level + 1, sb)  
        End If  
    Next  

End Sub  

public void IsCodeTypeExample(DTE2 dte)  
{  
    // NOTE: This example requires a reference to the System.Text   
    //       namespace.  

    // Before running this example, open a code document from a   
    // project.  
    ProjectItem item = dte.ActiveDocument.ProjectItem;  
    StringBuilder sb = new StringBuilder();  

    RecurseElements(item.FileCodeModel.CodeElements, 0, sb);  

    MessageBox.Show(item.Name + " contains the following elements:" +   
        Environment.NewLine + Environment.NewLine + sb.ToString());  
}  

void RecurseElements(CodeElements elems, int level, StringBuilder sb)  
{  
    foreach (CodeElement elem in elems)  
    {  
        // Add element to the list of names.  
        sb.Append(' ', level * 8);  
        sb.Append(elem.Name + " [" + elem.Kind.ToString() + "]" +   
            Environment.NewLine);  

        // Call this function recursively if element has children.  
        if (elem.Kind == vsCMElement.vsCMElementNamespace)  
            RecurseElements(((CodeNamespace)elem).Members,   
                level + 1, sb);  
        else if (elem.IsCodeType)  
            RecurseElements(((CodeType)elem).Members, level + 1, sb);  
    }  
}  

注解

如果是 true ，则可以查询接口或将其转换为 CodeType 对象。 当为、、、或时，此值为 true Kind vsCMElementClass vsCMElementInterface vsCMElementDelegate vsCMElementStruct vsCMElementEnum 。

备注

在进行了某些类型的编辑之后，代码模型元素（例如类、结构、函数、特性、委托等）的值可能变为非确定性的，这意味着不能确定它们的值始终保持不变。
