Expression.Call Method (Expression, MethodInfo, IEnumerable(Of Expression))
Creates a MethodCallExpression that represents a call to a method that takes arguments.
Assemblies: System.Core (in System.Core.dll)
System.Linq.Expressions (in System.Linq.Expressions.dll)
'Declaration Public Shared Function Call ( _ instance As Expression, _ method As MethodInfo, _ arguments As IEnumerable(Of Expression) _ ) As MethodCallExpression
- Type: System.Linq.Expressions.Expression
method is Nothing.
instance is Nothing and method represents an instance method.
instance.Type is not assignable to the declaring type of the method represented by method.
The number of elements in arguments does not equal the number of parameters for the method represented by method.
One or more of the elements of arguments is not assignable to the corresponding parameter for the method represented by method.
To represent a call to a static (Shared in Visual Basic) method, pass in Nothing for the instance parameter when you call this method, or call Call instead.
If method represents an instance method, the Type property of instance must be assignable to the declaring type of the method represented by method.
If arguments is not Nothing, it must have the same number of elements as the number of parameters for the method represented by method. Each element in arguments must not be Nothing and must be assignable to the corresponding parameter of method, possibly after quoting.
An element will be quoted only if the corresponding method parameter is of type Expression. Quoting means the element is wrapped in a Quote node. The resulting node is a UnaryExpression whose Operand property is the element of arguments.
