.NET Framework Class Library
AssemblyName Constructor (String)

Initializes a new instance of the AssemblyName class with the specified display name.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)
Visual Basic (Declaration)
Public Sub New ( _
    assemblyName As String _
)
Visual Basic (Usage)
Dim assemblyName As String

Dim instance As New AssemblyName(assemblyName)
C#
public AssemblyName(
    string assemblyName
)
Visual C++
public:
AssemblyName(
    String^ assemblyName
)
JScript
public function AssemblyName(
    assemblyName : String
)

Parameters

assemblyName
Type: System..::.String
The display name of the assembly, as returned by the FullName property.
ExceptionCondition
ArgumentNullException

assemblyName is nullNothingnullptra null reference (Nothing in Visual Basic).

ArgumentException

assemblyName is a zero length string.

The supplied assemblyName is parsed, and the appropriate fields of the new AssemblyName are initialized with values from the display name. This is the recommended way of parsing display names. Writing your own code to parse display names is not recommended.

The following code example creates a dynamic assembly named MyAssembly.exe and saves it to your hard disk. After running the example, you can use the MSIL Disassembler (Ildasm.exe) to examine the assembly metadata.
