C# Eval Expression LINQ Dynamic - Reverse

LINQ Dynamic Reverse Examples

C# Dynamic LINQ Reverse examples using an Expression Evaluator.

Reverse

This C# example uses the LINQ Where method with a dynamic expression to find all elements of an array less than 5.

LINQ

private void uiReverse_Simple_1_LINQ_Click(object sender, EventArgs e)
{
	string[] digits = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };

	var reversedIDigits = digits.Where(d => d[1] == 'i').Reverse();

	var sb = new StringBuilder();

	sb.AppendLine("A backwards list of the digits with a second character of 'i':");
		foreach (var d in reversedIDigits)
		{
			sb.AppendLine(d);
		}

	My.Result.Show(My.LinqResultType.Linq, uiResult, sb);
}

LINQ Execute

private void uiReverse_Simple_1_LINQ_Execute_Click(object sender, EventArgs e)
{
	string[] digits = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };

	var reversedIDigits = digits.Where(d => d[1] == 'i').Execute<IEnumerable<string>>("Reverse()");

	var sb = new StringBuilder();

	sb.AppendLine("A backwards list of the digits with a second character of 'i':");
		foreach (var d in reversedIDigits)
		{
			sb.AppendLine(d);
		}

	My.Result.Show(My.LinqResultType.LinqExecute, uiResult, sb);
}

Result

A backwards list of the digits with a second character of 'i':
nine
eight
six
five
