Examples
The following example creates a new namespace and attribute in the current class and lists some of the attribute's properties.
public void CreateClassAndAttrib(DTE2 applicationObject)  
{  
    // Before running, load or create a project.  
    FileCodeModel2 fcm2 = GetFileCodeModel(applicationObject);  
    CodeAttribute2 cmAttribute;  
    CodeClass2 cmClass;  
    String msg = null;  
    if (fcm2 != null)  
    {  
        CodeNamespace cmNamespace;  
        // Try to create a new namespace.  
        try  
        {  
            cmNamespace = fcm2.AddNamespace("CMNamespace", -1);  
            // If successful, create the other code elements.  
            if (cmNamespace != null)

                msg += "Attribute count: " +   
                cmAttribute.Collection.Count + Environment.NewLine;  
                msg += "Document name: " +

            {  
                MessageBox.Show("Cannot continue - no filecodemodel   
                available.");  
            }  
        }

    // window.

    if (txtWin != null)  
    {  
        try  
        {  
             fcm2 = (FileCodeModel2)txtWin.Parent.  
             ProjectItem.FileCodeModel;  
             return fcm2;  
        }  
        catch (Exception ex)  
        {  
             MessageBox.Show("ERROR: " + ex);

Remarks
In Visual Studio, the DTE is the root of the automation model, which other object models often call "Application".
Note
The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).
