Assembly.GetEntryAssembly Method (System.Reflection)

.NET Framework Class Library

Assembly..::.GetEntryAssembly Method

Gets the process executable in the default application domain. In other application domains, this is the first executable that was executed by AppDomain..::.ExecuteAssembly.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

Syntax

Public Shared Function GetEntryAssembly As Assembly

public static Assembly GetEntryAssembly()

public:
static Assembly^ GetEntryAssembly()

static member GetEntryAssembly : unit -> Assembly

Return Value

Type: System.Reflection..::.Assembly
The assembly that is the process executable in the default application domain, or the first executable that was executed by AppDomain..::.ExecuteAssembly. Can return nullNothingnullptra null reference (Nothing in Visual Basic) when called from unmanaged code.

Remarks

The GetEntryAssembly method can return nullNothingnullptra null reference (Nothing in Visual Basic) when a managed assembly has been loaded from an unmanaged application. For example, if an unmanaged application creates an instance of a COM component written in C#, a call to the GetEntryAssembly method from the C# component returns null, because the entry point for the process was unmanaged code rather than a managed assembly.
