MethodCallExpression Class

Represents calling a method.

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

public sealed class MethodCallExpression : Expression

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.

string[,] gradeArray =
    { {"chemistry", "history", "mathematics"}, {"78", "61", "82"} };

System.Linq.Expressions.Expression arrayExpression =
    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".
System.Linq.Expressions.MethodCallExpression 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)
