NameDescription
System_CAPS_pubmethod AssemblyCompanyAttribute

Initializes a new instance of the AssemblyCompanyAttribute class.

NameDescription
System_CAPS_pubproperty

Gets company name information.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The following example shows how to apply attributes, including the AssemblyCompanyAttribute attribute, to a dynamic assembly. The example saves the assembly to disk, and the attribute value can be viewed by using the Windows File Properties dialog.

class Example
{
   public static void Main()
   {
      AssemblyName assemName = new AssemblyName();
      assemName.Name = "EmittedAssembly";

      // Create a dynamic assembly in the current application domain,
      // specifying that the assembly is to be saved.
      //
      AssemblyBuilder myAssembly = 
         AppDomain.CurrentDomain.DefineDynamicAssembly(assemName, 
            AssemblyBuilderAccess.Save);


      // To apply an attribute to a dynamic assembly, first get the 
      // attribute type. The AssemblyFileVersionAttribute sets the 
      // File Version field on the Version tab of the Windows file
      // properties dialog.
      //
      Type attributeType = typeof(AssemblyFileVersionAttribute);

      // To identify the constructor, use an array of types representing
      // the constructor's parameter types. This ctor takes a string.
      //
      Type[] ctorParameters = { typeof(string) };

      // Get the constructor for the attribute.
      //
      ConstructorInfo ctor = attributeType.GetConstructor(ctorParameters);

      // Pass the constructor and an array of arguments (in this case,
      // an array containing a single string) to the 
      // CustomAttributeBuilder constructor.
      //
      object[] ctorArgs = { "2.0.3033.0" };
      CustomAttributeBuilder attribute = 
         new CustomAttributeBuilder(ctor, ctorArgs);

      // Finally, apply the attribute to the assembly.
      //
      myAssembly.SetCustomAttribute(attribute);


      // The pattern described above is used to create and apply
      // several more attributes. As it happens, all these attributes
      // have a constructor that takes a string, so the same ctorArgs
      // variable works for all of them.


      // The AssemblyTitleAttribute sets the Description field on
      // the General tab and the Version tab of the Windows file 
      // properties dialog.
      //
      attributeType = typeof(AssemblyTitleAttribute);
      ctor = attributeType.GetConstructor(ctorParameters);
      ctorArgs = new object[] { "The Application Title" };

      // The AssemblyDescriptionAttribute sets the Comment item.
      //
      attributeType = typeof(AssemblyDescriptionAttribute);
      ctor = attributeType.GetConstructor(ctorParameters);
      attribute = new CustomAttributeBuilder(ctor, 
         new object[] { "This is a comment." });
      myAssembly.SetCustomAttribute(attribute);

      // The AssemblyCompanyAttribute sets the Company item.
      //
      attributeType = typeof(AssemblyCompanyAttribute);
      ctor = attributeType.GetConstructor(ctorParameters);
      attribute = new CustomAttributeBuilder(ctor, 
         new object[] { "My Example Company" });
      myAssembly.SetCustomAttribute(attribute);

      // The AssemblyProductAttribute sets the Product Name item.
      //
      attributeType = typeof(AssemblyProductAttribute);
      ctor = attributeType.GetConstructor(ctorParameters);
      attribute = new CustomAttributeBuilder(ctor, 
         new object[] { "My Product Name" });
      myAssembly.SetCustomAttribute(attribute);


      // Define the assembly's only module. For a single-file assembly,
      // the module name is the assembly name.
      //
      ModuleBuilder myModule = 
         myAssembly.DefineDynamicModule(assemName.Name, 
            assemName.Name + ".exe");

      // No types or methods are created for this example.


      // Define the unmanaged version information resource, which
      // contains the attribute informaion applied earlier, and save
      // the assembly. Use the Windows Explorer to examine the properties
      // of the .exe file.
      //
      myAssembly.DefineVersionInfoResource();
      myAssembly.Save(assemName.Name + ".exe");
