MethodCallExpression Class
Visual Studio 2008
Represents calling a method.
Assembly: System.Core (in System.Core.dll)
Use the Call, ArrayIndex, or ArrayIndex factory method to create a MethodCallExpression.
The value of the NodeType property of a MethodCallExpression object is Call.
The following example creates a MethodCallExpression object that represents indexing into a two-dimensional array.
Dim gradeArray(,) As String = _ {{"chemistry", "history", "mathematics"}, {"78", "61", "82"}} Dim arrayExpression As System.Linq.Expressions.Expression = _ System.Linq.Expressions.Expression.Constant(gradeArray) ' Create a MethodCallExpression that represents indexing ' into the two-dimensional array 'gradeArray' at (0, 2). ' Executing the expression would return "mathematics". Dim methodCallExpression As System.Linq.Expressions.MethodCallExpression = _ System.Linq.Expressions.Expression.ArrayIndex( _ arrayExpression, _ System.Linq.Expressions.Expression.Constant(0), _ System.Linq.Expressions.Expression.Constant(2)) Console.WriteLine(methodCallExpression.ToString()) ' This code produces the following output: ' ' value(System.String[,]).Get(0, 2)
