= Operator

The assignment operator (=) stores the value of its right-hand operand in the storage location, property, or indexer denoted by its left-hand operand and returns the value as its result. The operands must be of the same type (or the right-hand operand must be implicitly convertible to the type of the left-hand operand).

lhs = expr


A storage location, property, or indexer.
An expression.


The assignment operator cannot be overloaded.


// cs_operator_assignment.cs
using System;
class Test 
   public static void Main() 
      double x;
      int i;
      i = 5; // int to int assignment
      x = i; // implicit conversion from int to double
      i = (int)x; // needs cast
      Console.WriteLine("i is {0}, x is {1}", i, x);
      object obj = i;
      Console.WriteLine("boxed value = {0}, type is {1}",
         obj, obj.GetType());
      i = (int)obj;
      Console.WriteLine("unboxed: {0}", i);


i is 5, x is 5
boxed value = 5, type is System.Int32
unboxed: 5
