Get Assembly info of my current C# Application

Question

Hello, developers...

How can i get the assembly information of my current C# application, for example its GUID?

 

Thanks,

Amin Mashayekhi

Answer 1

You can get at this by reflecting on the assembly:

 

Code Snippet

Guid assemblyGuid = Guid.Empty;

object[] assemblyObjects =

System.Reflection.Assembly.GetEntryAssembly().GetCustomAttributes(

typeof(System.Runtime.InteropServices.GuidAttribute), true);

if (assemblyObjects.Length > 0)

{

assemblyGuid = new Guid(((System.Runtime.InteropServices.GuidAttribute)assemblyObjects[0]).Value);

}

 

 

You can get at other attributes in a similar fashion.

Answer 2

Here's a little helper method that does the same as Dan Rigsby's code:

 

Code Snippet

public static T GetAssemblyAttribute<T>(Assembly assembly) where T : Attribute

{

    if (assembly == null) return null;

    object[] attributes = assembly.GetCustomAttributes(typeof(T), true);

    if (attributes == null) return null;

    if (attributes.Length == 0) return null;

    return (T)attributes[0];

}

 

Answer 3

I got a set of helper classes like that in a library too.  I wish they would have added more generics support in methods like these.  They are helpful!

 

Answer 4

Thanks for the information above everyone.  I've written a C# AssemblyInfo class to easily retrieve the information...

Hi All,

A bit late in the post, but it helped us super. I've removed some of the redundant code in mddubs class (thanks for that mmdubs):

 

using System;
using System.Diagnostics;
using System.Reflection;

namespace Diartis.KLIB.KLIBLibrary
{
	public class AssemblyInfoHelper
	{
		private static Assembly m_Assembly;

		public AssemblyInfoHelper(Type type)
		{
			Assertions.CheckObject("type", type);
			m_Assembly = Assembly.GetAssembly(type);
			Assertions.CheckObject("m_Assembly", m_Assembly);
		}

		private T CustomAttributes<T>()
			where T : Attribute
		{
			object[] customAttributes = m_Assembly.GetCustomAttributes(typeof(T), false);

			if ((customAttributes != null) && (customAttributes.Length > 0))
			{
				return ((T)customAttributes[0]);
			}

			throw new InvalidOperationException();
		}

		public string Title
		{
			get
			{
				return CustomAttributes<AssemblyTitleAttribute>().Title;
			}
		}

		public string Description
		{
			get
			{
				return CustomAttributes<AssemblyDescriptionAttribute>().Description;
			}
		}

		public string Company
		{
			get
			{
				return CustomAttributes<AssemblyCompanyAttribute>().Company;
			}
		}

		public string Product
		{
			get
			{
				return CustomAttributes<AssemblyProductAttribute>().Product;
			}
		}

		public string Copyright
		{
			get
			{
				return CustomAttributes<AssemblyCopyrightAttribute>().Copyright;
			}
		}

		public string Trademark
		{
			get
			{
				return CustomAttributes<AssemblyTrademarkAttribute>().Trademark;
			}
		}

		public string AssemblyVersion
		{
			get
			{
				return m_Assembly.GetName().Version.ToString();
			}
		}

		public string FileVersion
		{
			get
			{
				FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(m_Assembly.Location);
				return fvi.FileVersion;
			}
		}

		public string Guid
		{
			get
			{
				return CustomAttributes<System.Runtime.InteropServices.GuidAttribute>().Value;
			}
		}

		public string FileName
		{
			get
			{
				FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(m_Assembly.Location);
				return fvi.OriginalFilename;
			}
		}

		public string FilePath
		{
			get
			{
				FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(m_Assembly.Location);
				return fvi.FileName;
			}
		}
	}
}

Answer 6

Paul - where are you getting "Assertions" from?

 

Thanks (and sorry for beating a dead thread)

Check out Microsoft.VisualBasic.ApplicationServices.AssemblyInfo
