A pointer has its own memory address and size on the stack (4 bytes on x86), whereas a reference shares the same memory address (with the original variable) but also takes up some space on the stack. Since a reference has the same address as the original variable itself, it is safe t...

Difference Between Pointer and Reference It is not possible to refer directly to a reference object after it is defined; any occurrence of its name refers directly to the object it references. Once a reference is created, it cannot be later made to reference another object; it cannot be rese...
is that reference is an object containing information which refers to data stored elsewhere, as opposed to containing the data itself while pointer is a variable that holds the address of a memory location where a value can be stored. As nouns the difference between reference and pointer is tha...
T2>delegate. A lambda expression that has one parameter and returns a value can be converted to aFunc<T,TResult>delegate. In the following example, the lambda expressionx => x * x, which specifies a parameter namedxand returns the value ofxsquared, is assigned to a variable of a ...
a value and is named MYEXAMPLE. (This is in fact a variable). We also have a pointer MYPOINT. In this case, our pointer MYPOINT contains the address 0x2000. This is the address of MYEXAMPLE so we say MYPOINT points to MYEXAMPLE. So there is the pointer and the value pointed to....
A function returns a pointer to a local variable. A function performs the assignment globPtr = &locVar. globPtr is a global pointer variable and locVar is a local variable. A function performs the assignment *paramPtr = &locVar. paramPtr is a function parameter that is, for instance, ...
Reference variablesare the alias of another variable while pointer variable are the special type of variable that contains the address of another variable. Reference and pointers both can be used to refer the actual variable they provide the direct access to the variable. ...
The `is` and `as` operators test the type of an object. The `typeof` keyword returns the type of a variable. Casts try to convert an object to a variable of a different type.
