Expression::Call Method (Type^, String^, array<Type^>^, array<Expression^>^)

.NET Framework (current version)

Creates a MethodCallExpression that represents a call to a static (Shared in Visual Basic) method by calling the appropriate factory method.

Namespace: System.Linq.Expressions
Assembly: System.Core (in System.Core.dll)

Syntax

C++

public:
static MethodCallExpression^ Call(
	Type^ type,
	String^ methodName,
	array<Type^>^ typeArguments,
	... array<Expression^>^ arguments
)

Parameters

type: Type: System::Type^
The Type that specifies the type that contains the specified static (Shared in Visual Basic) method.

methodName: Type: System::String^
The name of the method.

typeArguments: Type: array<System::Type^>^
An array of Type objects that specify the type parameters of the generic method. This argument should be null when methodName specifies a non-generic method.

arguments: Type: array<System.Linq.Expressions::Expression^>^
An array of Expression objects that represent the arguments to the method.

Return Value

Type: System.Linq.Expressions::MethodCallExpression^

A MethodCallExpression that has the NodeType property equal to Call, the Method property set to the MethodInfo that represents the specified static (Shared in Visual Basic) method, and the Arguments property set to the specified arguments.

Exceptions

Exception	Condition
ArgumentNullException	type or methodName is null.
InvalidOperationException	No method whose name is methodName, whose type parameters match typeArguments, and whose parameter types match arguments is found in type or its base types. -or- More than one method whose name is methodName, whose type parameters match typeArguments, and whose parameter types match arguments is found in type or its base types.

Remarks

The Type property of the resulting MethodCallExpression is equal to the return type of the method denoted by methodName. The Object property is null.
