AssemblyName.Flags Property

Gets or sets the attributes of the assembly.

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

public AssemblyNameFlags Flags { get; set; }

Property Value

Type: System.Reflection.AssemblyNameFlags
A value that represents the attributes of the assembly.

The following example emits a dynamic assembly and saves it to the current directory. When the assembly is created, the Flags property is used to specify that the assembly has a public key.
