==Aliasing Class Names==

<source lang="csharp">using Class1 = Namespace1.TestClass;
using Class2 = Namespace2.TestClass;

namespace Namespace1
{
class TestClass
{
public TestClass()
{
System.Console.WriteLine("Hello from Namespace1.TestClass!");
}
}
}

namespace Namespace2
{
class TestClass
{
public TestClass()
{
System.Console.WriteLine("Hello from Namespace2.TestClass!");
}
}
}

class MainClass
{
public static void Main()
{
Class1 Object1 = new Class1();
Class2 Object2 = new Class2();
}
}</source>

==Aliasing Namespace Names==

<source lang="csharp">using N1 = Namespace1;
using N2 = Namespace2;

namespace Namespace1
{
class TestClass
{
public TestClass()
{
System.Console.WriteLine("Hello from Namespace1.TestClass!");
}
}
}

namespace Namespace2
{
class TestClass
{
public TestClass()
{
System.Console.WriteLine("Hello from Namespace2.TestClass!");
}
}
}

class MainClass
{
public static void Main()
{
N1.TestClass Object1 = new N1.TestClass();
N2.TestClass Object2 = new N2.TestClass();
}
}</source>

==Global Namespace Alias==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Text;
using System.ruponentModel;
class Configuration {}
namespace My
{
class Configuration {}
class GlobalNamespaceAlias
{
static void Main()
{
Console.WriteLine(typeof(Configuration));
Console.WriteLine(typeof(global::Configuration));
Console.WriteLine(typeof(global::My.GlobalNamespaceAlias));
}
}
}</source>

==Simple Aliases for namespace==

<source lang="csharp">using System;
using WinForms = System.Windows.Forms;
using WebForms = System.Web.UI.WebControls;
using System.ruponentModel;
class SimpleAliases
{
static void Main()
{
Console.WriteLine (typeof (WinForms.Button));
Console.WriteLine (typeof (WebForms.Button));
}
}</source>

==Use the global alias.==

<source lang="csharp">using System;

using Ctr = Counter;

namespace Counter {
class MyClass {
}
}

// Declare another class called CountDown, which
// is in the global namespace.
class MyClass {
}

class GlobalAliasQualifierDemo {
public static void Main() {

Ctr::MyClass m = new Ctr::MyClass();

// Next, create CountDown object from global namespace.
global::MyClass m2 = new global::MyClass();
}
}</source>

==Using a Namespace Directive==

<source lang="csharp">using System;

using Class1 = Namespace1.TestClass;
using Class2 = Namespace2.TestClass;

namespace Namespace1
{
class TestClass
{
public TestClass()
{
Console.WriteLine("Hello from Namespace1.TestClass!");
}
}
}

namespace Namespace2
{
class TestClass
{
public TestClass()
{
Console.WriteLine("Hello from Namespace2.TestClass!");
}
}
}

class MainClass
{
public static void Main()
{
Class1 Object1 = new Class1();
Class2 Object2 = new Class2();
}
}</source>

==Using the alias keyword to refer to a nested namespace.==

<source lang="csharp">using CmpDb = Company.InternalClasses.Database.Table;
namespace Company.InternalClasses {
public class DBInterface {
public static void Open() {
System.Console.WriteLine("Opening database");
}
}
// Define a nested namespace within InternalClasses
namespace Database {
public class Table {
public static void Open(string tblName) {
System.Console.WriteLine("Opening table {0}", tblName);
}
}
}
}
public class MainClass {
public static void Main() {
CmpDb.Open("fred");
}
}</source>
