AssemblyName.Flags Property

Definition

Gets or sets the attributes of the assembly.

C#
public System.Reflection.AssemblyNameFlags Flags { get; set; }

Property Value

A value that represents the attributes of the assembly.

Examples

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.
