Static constructors

Destructors

Except for destructors and static constructors (which cannot be invoked explicitly), the statements contained in function members are executed through function member invocations. The actual syntax for writing a function member invocation depends on the particular function member category.

The argument list (§‎7.4.1) of a function member invocation provides actual values or variable references for the parameters of the function member.

Invocations of methods, indexers, operators and instance constructors employ overload resolution to determine which of a candidate set of function members to invoke. This process is described in §‎7.4.2.

Once a particular function member has been identified at compile-time, possibly through overload resolution, the actual run-time process of invoking the function member is described in §‎7.4.3.

The following table summarizes the processing that takes place in constructs involving the six categories of function members that can be explicitly invoked. In the table, e, x, y, and value indicate expressions classified as variables or values, T indicates an expression classified as a type, F is the simple name of a method, and P is the simple name of a property.

Description

Method invocation

F(x, y)

Overload resolution is applied to select the best method F in the containing class or struct. The method is invoked with the argument list (x, y). If the method is not static, the instance expression is this.

T.F(x, y)

Overload resolution is applied to select the best method F in the class or struct T. A compile-time error occurs if the method is not static. The method is invoked with the argument list (x, y).

e.F(x, y)

Overload resolution is applied to select the best method F in the class, struct, or interface given by the type of e. A compile-time error occurs if the method is static. The method is invoked with the instance expression e and the argument list (x, y).

Property access

P

The get accessor of the property P in the containing class or struct is invoked. A compile-time error occurs if P is write-only. If P is not static, the instance expression is this.

P = value

The set accessor of the property P in the containing class or struct is invoked with the argument list (value). A compile-time error occurs if P is read-only. If P is not static, the instance expression is this.

T.P

The get accessor of the property P in the class or struct T is invoked. A compile-time error occurs if P is not static or if P is write-only.

T.P = value

The set accessor of the property P in the class or struct T is invoked with the argument list (value). A compile-time error occurs if P is not static or if P is read-only.
