What is type safe?

.NET delegates are type safe. If you will attempt to pass a delegate, a method that does not "match the pattern", you will receive a compile time error "Method does not match delegate pattern!". (More...)

Decorator Pattern design pattern that is type-safe and still extensible on runtime (More...)

When you deploy a WebPart to SharePoint, you must first make it as a safe control to use within SharePoint in the web.config file. Entries made in the safe controls element of SharePoint are encountered by the SharePointHandler object and will be loaded in the SharePoint environment properly, those not will not be loaded and will throw an error.
In the generic safe control entry (this is general, there could be more), there is generally the Assembly name, the namespace, the public key token numeric, the typename, and the safe declaration (whether it is safe or not). There are other optional elements. (More...)

No, ArrayList is not a type safe collection because it allows you to add a any object. That means if you have one arrayList class object you can add in Integer, string, boolean, double etc value into one ArrayList class object.

for eg

ArrayList arr = new ArrayList();
arr("One");
arr.Add(1);
arr.Add(true); (More...)

(Class constructor method is also known as type constructor or type initializer)
Instance constructor is executed when a new instance of type is created and the class constructor is executed after the type is loaded and before any one of the type members is accessed. (It will get executed only 1st time, when we call any static methods/fields in the same class.) Class constructors are used for static field initialization. Only one class constructor per type is permitted, and it cannot use the vararg (variable argument) calling convention. (More...)

The goal of type system unification is to bridge the gap between value types and reference types that exists in most languages. For example, a Stack class can provide Push and Pop methods that take and return object values.

public class Stack
{
public object Pop() {...}
public void Push(object o) {...}
}
Because C# has a unified type system, the Stack class can be used with elements of any type, including value types like int. (More...)
