public override void Install (System.Collections.IDictionary savedState);
override this.Install : System.Collections.IDictionary -> unit
Public Overrides Sub Install (savedState As IDictionary)

Parameters

savedState
IDictionary

An IDictionary used to save information needed to perform a commit, rollback, or uninstall operation.

Exceptions

ArgumentException

The savedState parameter is null.

-or-

A file could not be found.

Exception

An exception occurred in the BeforeInstall event handler of one of the installers in the collection.

-or-

An exception occurred in the AfterInstall event handler of one of the installers in the collection.

-or-

Installer types were not found in one of the assemblies.

Examples

The following example demonstrates the AssemblyInstaller constructor and the Install and Commit methods of the AssemblyInstaller class.

An object of the AssemblyInstaller class is created by invoking the AssemblyInstaller constructor. The properties of this object are set and the Install and Commit methods are called to install the 'MyAssembly_Install.exe' assembly.

      array<String^>^myString = {"/logFile=example.log"};
      
      // Create an Object* of the 'AssemblyInstaller' class.
      AssemblyInstaller^ myAssemblyInstaller = gcnew AssemblyInstaller;

Remarks

This method calls the Install method of each installer contained in the Installers property of this instance. The IDictionary object specified by the savedState parameter is updated to reflect the status of the installation after the contained installers have run. If all the Install methods succeed, the Commit method is called. Otherwise, the Rollback method is called.

Notes to Callers

The IDictionary specified by the savedState parameter should be empty when passed to the Install(IDictionary) method.
