Questions tagged [anonymous-methods]

An anonymous method is a procedure or function that does not have a name associated with it.

An anonymous method is a procedure or function that does not have a name associated with it. An anonymous method treats a block of code as an entity that can be assigned to a variable or used as a parameter to a method. In addition, an anonymous method can refer to variables and bind values to the variables in the context in which the method is defined. They are similar to the construct of closures defined in some languages.

An anonymous method in C# is a way to pass a code block as a delegate parameter.
