Part # Tutorial Why Enums

Enums is strongly typed constants.

If a program uses set of integral numbers, consider replacing them with enums. Otherwise the Pragram becomes less

Readable maintainable

Part Tutorial C # Enums Example

public enum gender

{

Male

Female

}

Part Tutorial C # Enums in C #

1,enums is enumerations.

2,enums is strongly typed constants (constant). Hence (therefore), an explicit (explicit) cast is needed to convert the from enum type to an integral type and vice versa. Also, an enum of one TPE cannot is implicitly (implicit) assigned (designation) to an enum of another type even though the underlying Valu E of their members is the same.

3,the default underlying type of an enum is int.

4, the Defalut value for first element is ZERO and gets incremented (incremented) by 1.

5,it is possible to customize the underlying type and values.

6,enums is value types.

7,enum keyword (all small letteres) are used to create enumerations, where as Enum class,contains static GetValues () and Get Names () methods which can be used to list Enum underlying type values and Names.

Part Tutorial C # Reflection Example

Here is the code

private void Btndiscover_click (object sender, EventArgs e)
{
LbMethods.Items.Clear ();
LbProperties.Items.Clear ();
LbConstructor.Items.Clear ();
String typeName = TxtTypeName.Text.Trim ();
Type t = Type.GetType (typeName);
if (t = = null)
{
MessageBox.Show ("Type is No Exit, please Enter A right type!", "warnning", MessageBoxButtons . OK);
Txttypename.clear ();
Txttypename.focus ();
}
Else
{
Methodinfo[] methods = T.getmethods ();
Propertyinfo[] Properties = t.getproperties ();
Constructorinfo[] constructors = t.getconstructors ();
foreach (Var method in methods)
{
LbMethods.Items.Add (string. Concat (method. Returntype.name, "", Method. Name));
}
foreach (var property in properties)
{
LbProperties.Items.Add (string. Concat (property. Propertytype.name, "", property. Name));
}
foreach (Var constructor in constructors)
{
LbConstructor.Items.Add (constructor. ToString ());
}
}
}
