Adds a project to the solution that is based on a project file already stored in the system.

Namespace: EnvDTE80
Assembly: EnvDTE80 (in EnvDTE80.dll)

Syntax

'Declaration
Function AddFromFile ( _
    FileName As String, _
    Exclusive As Boolean _
) As Project

Project AddFromFile(
    string FileName,
    bool Exclusive
)

Project^ AddFromFile(
    [InAttribute] String^ FileName, 
    [InAttribute] bool Exclusive
)

abstract AddFromFile : 
        FileName:string * 
        Exclusive:bool -> Project

function AddFromFile(
    FileName : String, 
    Exclusive : boolean
) : Project

Parameters

FileName
Type: System.String

Required. The full path and file name of the project file.

Exclusive
Type: System.Boolean

Optional. Indicates whether the project loads in the current solution or its own solution; true if the current solution is closed and the project is added to a new solution, false if the project is added to the existing, open solution.

Return Value

Type: EnvDTE.Project
A Project object.

Remarks

You can use the LaunchWizard method rather than AddFromFile to execute a wizard if you want to suppress its user interface (UI) during execution. LaunchWizard has a parameter that allows you to disable the UI.

Examples

For information on how to run this add-in code, see How to: Compile and Run the Automation Object Model Code Examples.

The following example shows how to create a solution and add an existing project to it.

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)
    AddFromFileExample(_applicationObject)
End Sub

Sub AddFromFileExample(ByVal dte As DTE2)
    ' This add-in creates a solution and adds an 
    ' existing project to it.
    Try
        Dim soln As Solution2 =  _
        CType(_applicationObject.Solution, Solution2)
        ' Create a new solution.
        ' Make sure the path below exists on your computer.
        ' You can modify the path.
        soln.Create("c:\temp2", "MyNewSolution")
        ' Add an existing project to the new solution.
        ' Modify the path to a location that contains a
        ' Visual Studio project.
        soln.AddFromFile _
        ' Make sure to set the path below to the default project location on your computer
        ("c:\temp1\Visual Studio 2010\ _  
        Projects\ConsoleApplication\ConsoleApplication\ _
        ConsoleApplication.csproj")
    Catch ex As System.Exception
        MsgBox(ex.ToString)
    End Try
End Sub

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.
    AddFromFileExample((DTE2)_applicationObject);
}
public void AddFromFileExample(DTE2 dte)
{
    // This add-in creates a soultion and adds an 
    // existing project to it. 
    try
    {
        Solution2 soln = (Solution2)_applicationObject.Solution;
        // Create a solution.
        // Make sure that the file path specified below
        // exists on your computer.
        // You can modify the path.
        soln.Create("c:\temp2", "MyNewSolution");
        // Add an existing project to the new solution.
        // Modify the path to a location that contains
        // a Visual Studio project.
        soln.AddFromFile("c:\temp1"
\Visual Studio 2010\Projects\ConsoleApplication
\ConsoleApplication\ ConsoleApplication.csproj", true);
        }
    catch(SystemException ex)
    {
        MessageBox.Show("ERROR: " + ex);
    }
}
