C# unit test using Moq verify property has been set

C# > Unit test > Moq > Verify property has been set

SetupSet : Specifies a setup on the mocked type for a call to a property setter.

VerifySet : Verifies that a property has been set on the mock, regardless of its value.

Example

using System;

namespace UnitTestProject1

{

    public interface Interface1

    {

        int Id { get; set; }

    }

}

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Moq;

namespace UnitTestProject1

{

    [TestClass]

    public class UnitTest1

    {

        [TestMethod]

        public void TestMethod1()

        {

            var mocker = new Mock<Interface1>();

            mocker.SetupSet(x => x.Id = 1);

            mocker.Object.Id = 1;

            mocker.VerifySet(x => x.Id);

        }

    }

}

Convert string to date C# example

C# > System Namespace > DateTime > Parse

Parse converts string to a date.

Example

string value = "5/15/2015";

var dte = DateTime.Parse(value, CultureInfo.InvariantCulture); // {5/15/2015 12:00:00 AM}

Find last row Telerik RadGridView

Telerik > RadGridView > Find last row

GridViewRowInfo lastRow = radGridView.Rows[radGridView.Rows.Count - 1];
lastRow.IsSelected = true;

C# Generic Interface Example

C# > Generics > Generic Interface 

Example

class Serializer1 { public string Name { get; set; } };

class Serializer2 { public string Name { get; set; } };

interface GenericSerializer<T>

{

      string Name(T tValue);

}

class Serializer<T>: GenericSerializer<T>

{

public string Name(T tValue)

        {

            var prop = tValue.GetType().GetProperty("Name");

            return prop.GetValue(tValue, null) as string;

        }

}

Serializer1 s1 = new Serializer1() { Name = "Serializer1" };

Serializer2 s2 = new Serializer2() { Name = "Serializer2" };

Serializer<Serializer1> serializer1 = new Serializer<Serializer1>();

string name1 = serializer1.Name(s1);

Serializer<Serializer2> serializer2 = new Serializer<Serializer2>();

string name2 = serializer2.Name(s2);

LINQ Average excluding or including zeros c#

C# > LINQ > Average


Average computes the average of a sequence of numeric values.

Example

int[] int_array = new int[] { 5, 4, 2, 8, 10, 0 };

// linq average excluding zeros

double avg =

       (from ord in int_array

        where ord > 0

        select ord).Average();  // 5.8

// linq average including zeros 

avg =

       (from ord in int_array

       select ord).Average();    // 4.83

UPDATE SQL Server Example

SQL Server > DML > UPDATE

Changes existing data in a table or view.


Example

   person
set
   name = 'Bill'
where

Reflection to find all classes implementing interface c#

C# > Reflection >  Find classes implementing interface

var iTtype = typeof(Interface);

var types = AppDomain.CurrentDomain.GetAssemblies()

           .SelectMany(a => a.GetTypes())

           .Where(t => iTtype.IsAssignableFrom(t));
