Type extensions

#####TypeExtensions.CreateInstance

Given a Type variable:

var userType = typeof(User);

Instead of:

var user = (User)Activator.CreateInstance(userType);

We can write:

var user = (User)userType.CreateInstance();
//or
var user = userType.CreateInstance<User>();

#####TypeExtenstions.IsIEnumerable

Given:

var enumerableType = typeof(IEnumerable<string>);

Instead of:

if (typeof(IEnumerable).IsAssignableFrom(enumerableType))
{
    //do something
}

We can write:

if (enumerableType.IsIEnumerable())
{
    //do something
}

#####TypeExtenstions.IsIList

Given:

var listType = typeof(IList);

Instead of:

if (typeof(IList).IsAssignableFrom(listType))
{
    //do something
}

We can write:

if (listType.IsIList())
{
    //do something
}

#####TypeExtenstions.IsString

Given:

var type = typeof(string);

Instead of:

if (typeof(string) == type)
{
    //do something
}

We can write:

if (type.IsString())
{
    //do something
}

#####TypeExtenstions.IsType

Given:

var type = typeof(Type);

Instead of:

if (typeof(Type) == type)
{
    //do something
}

We can write:

if (type.IsType())
{
    //do something
}
