通过

Solution2.IsOpen 属性

  • 项目

获取一个值，该值指示解决方案是否已打开。

命名空间：  EnvDTE80
程序集：  EnvDTE80（在 EnvDTE80.dll 中）

语法

声明
ReadOnly Property IsOpen As Boolean

bool IsOpen { get; }

property bool IsOpen {
    bool get ();
}

abstract IsOpen : bool with get

function get IsOpen () : boolean

属性值

类型：Boolean
如果解决方案已打开，则为 true；否则为 false。

备注

打开的解决方案不一定有解决方案 (.sln) 文件，因为它可能尚未保存。

示例

有关如何运行此外接程序代码的信息，请参见如何：编译和运行自动化对象模型代码示例。

下面的示例显示解决方案的打开 (IsOpen) 状态。

Public Sub OnConnection(ByVal application As Object, _
 ByVal connectMode As ext_ConnectMode, ByVal addInInst As Object, _
 ByRef custom As Array) Implements IDTExtensibility2.OnConnection
    _applicationObject = CType(application, DTE2)
    _addInInstance = CType(addInInst, AddIn)
    IsOpenExample(_applicationObject)
End Sub

Sub IsOpenExample(ByVal dte As DTE2)
    ' This add-in displays the IsOpen status of the solution.
    ' Open a solution in 
    ' Visual Studio before running this example.
    Try
        Dim soln As Solution2 = CType _
        (_applicationObject.Solution, Solution2)
        Dim solnName As String = _
        System.IO.Path.GetFileNameWithoutExtension(soln.FullName)
        MsgBox("Solution " & solnName & _
        " has the following IsOpen state:" & _
        vbCrLf & vbCrLf & soln.IsOpen.ToString())
    Catch ex As System.Exception
        MsgBox(ex.ToString)
    End Try
End Sub

//you will need to add this reference to your project as well
using System.Windows.Forms;
public void OnConnection(object application,
 Extensibility.ext_ConnectMode connectMode, object addInInst,
 ref System.Array custom)
{
    _applicationObject = (DTE2)application;
    _addInInstance = (AddIn)addInInst;
    // Pass the applicationObject member variable to the code example.
    IsOpenExample((DTE2)_applicationObject);
}
public void IsOpenExample(DTE2 dte)
{
    // This add-in determines if a solution is open. 
    // Open a solution in 
    // Visual Studio before running this example.
    try
    {
        Solution2 soln = (Solution2)_applicationObject.Solution;
        string solnName =
 System.IO.Path.GetFileNameWithoutExtension(soln.FullName);
        MessageBox.Show("Solution " + solnName + " IsOpen status is: "
 + soln.IsOpen.ToString());
    }
    catch(SystemException ex)
    {
        MessageBox.Show("ERROR: " + ex);
    }
}
