SPSolutionCollection class

Represents a collection of SPSolution objects.

Namespace:  Microsoft.SharePoint.Administration
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public sealed class SPSolutionCollection : SPPersistedChildCollection<SPSolution>, 
	IBackupRestoreConfiguration, IBackupRestore

Use the Solutions property of the SPFarm class to get the collection of solutions installed in the server farm. To add a solution to the collection, use the Add method.

Important noteImportant

Using the SPSolution constructor to create a solution object is not supported and returns a NullReferenceException if you attempt to implement members of an object created through the constructor.

Use an indexer to return a single solution from the collection. For example, if the collection is assigned to a variable named myDefinitions, use myDefinitions[index] in C#, or myDefinitions(index) in Visual Basic, where index is the GUID of the Solution.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
