How can I retrieve the namespace to a string C#
C#StringNamespacesC# Problem Overview
I am writing a program which needs the namespace of the program but I cant seem to figure out how to retrieve it. I would like the end result to be in a string.
I was able to find an MSDN page about this topic but it proved to be unhelpful to myself. http://msdn.microsoft.com/en-us/library/system.type.namespace.aspx
Any help would be appreciated. The program is written in C#.
EDIT: Sorry guys, this is not a console application.
C# Solutions
Solution 1 - C#
This should work:
var myType = typeof(MyClass);
var n = myType.Namespace;
Write out to the console:
Type myType = typeof(MyClass);
Console.WriteLine("Namespace: {0}.", myType.Namespace);
Setting a WinForm label:
Type myType = typeof(MyClass);
namespaceLabel.Text = myType.Namespace;
Or create a method in the relevant class and use anywhere:
public string GetThisNamespace()
{
return GetType().Namespace;
}
Solution 2 - C#
To add to all the answers.
Since C# 6.0 there is the nameof keyword.
string name = nameof(MyNamespace);
This has several advantages:
- The name is resolved at compile-time
- The name will change when refactoring the namespace
- It is syntax checked, so the name must exist
- cleaner code
Note: This doesn't give the full namespace though. In this case, name
will be equal to Bar
:
namespace Foo.Bar
{
string name = nameof(Foo.Bar);
}
Solution 3 - C#
Put this to your assembly:
public static string GetCurrentNamespace()
{
return System.Reflection.Assembly.GetExecutingAssembly().EntryPoint.DeclaringType.Namespace;
}
Or if you want this method to be in a library used by your program, write it like this:
[System.Runtime.CompilerServices.MethodImpl(MethodImplOptions.NoInlining)]
public static string GetCurrentNamespace()
{
return System.Reflection.Assembly.GetCallingAssembly().EntryPoint.DeclaringType.Namespace;
}
Solution 4 - C#
This can't go wrong:
MethodBase.GetCurrentMethod().DeclaringType.Namespace
Solution 5 - C#
if you have item x
of class A
in namespace B
you can use:
string s = x.GetType().Namespace;
no s
contains "B"
you can also use x.GetType().Name
to get the type name or x.GetType().FullName
to get both
Solution 6 - C#
You could simply use typeof and then pass in the class (I.e. Program):
Console.WriteLine(typeof(Program).Namespace);
Which would print:
ConsoleApplication1
Solution 7 - C#
Type myType = typeof(MyClass);
// Get the namespace of the myClass class.
Console.WriteLine("Namespace: {0}.", myType.Namespace);
Building on Joe's comment you can still use
Type myType = typeof(MyClass);
// Get the namespace of the myClass class.
var namespaceName = myType.Namespace.ToString();
with namespaceName
being a variable to access the namespace name as a string value.
Solution 8 - C#
If you're executing it from a class in the namespace you need to capture then you can just use:
GetType().Namespace
This works nicely as it then allows you to refactor the namespace and will still work.
Solution 9 - C#
as a roll upp all post answers: getting all columns' values from a table given as a string tableName:
var tableName = "INVENTORY_PRICE";
var assembly = Assembly.GetExecutingAssembly();
var tip = typeof(Form3);
var t = assembly.GetType(tip.Namespace + "." + tableName);
if (t != null)
{
var foos = db.GetTable(t);
foreach (var f in foos)
{
Console.WriteLine(f + ":");
foreach (var property in f.GetType().GetProperties())
if (property != null)
{
var pv = property.GetValue(f, null);
Console.WriteLine(" " + property.Name + ":" + pv);
}
Console.WriteLine("------------------------------------------------");
}
}
it is very easy if we use ado, this sample uses LINQ context...
