TypeBuilder is a class in the System.Reflection.Emit namespace of C#. It is used to create new types at runtime. The package library for TypeBuilder is System.Reflection.Emit.

Example 1: Creating a new class at runtime using TypeBuilder

AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
AppDomain currentDomain = AppDomain.CurrentDomain;
AssemblyBuilder assemblyBuilder = currentDomain.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);

ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule");
TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicClass");

typeBuilder.DefineField("MyField", typeof(string), FieldAttributes.Public);

Type myType = typeBuilder.CreateType();
Console.WriteLine(myType.Name);

In this example, we create a new assembly and a new module using DefineDynamicAssembly and DefineDynamicModule methods. After that, we create a new class using the DefineType method. The class has a public string field named MyField. Finally, we create the type using the CreateType method and print the type's name.

Example 2: Creating a new interface at runtime using TypeBuilder

AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
AppDomain currentDomain = AppDomain.CurrentDomain;
AssemblyBuilder assemblyBuilder = currentDomain.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);

ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule");
TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicInterface", TypeAttributes.Interface | TypeAttributes.Abstract | TypeAttributes.Public);

typeBuilder.DefineMethod("MyMethod", MethodAttributes.Public | MethodAttributes.Abstract);

Type myType = typeBuilder.CreateType();
Console.WriteLine(myType.Name);

In this example, we create a new assembly and a new module. Then we create a new interface using the DefineType method with TypeAttributes.Interface, TypeAttributes.Abstract, and TypeAttributes.Public flags. The interface has a public abstract method named MyMethod. Finally, we create the type using the CreateType method and print the type's name.
