    ' Open a solution in   
    ' Visual Studio before running this example.

//you will need to add this reference to your project as well  
using System.Windows.Forms;

    // 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);  
    }  
}  

Remarks

An open solution does not necessarily have a solution (.sln) file, because it might not have been saved yet.
