The AssemblyName object contains information about an assembly, which you can use to bind to that assembly. An assembly’s identity consists of the following:

·         simple name

·         version number

·         cryptographic key pair

·         supported culture

The simple name is typically the file name for the manifest file without its extension. The key pair includes a public and private key, used to create strong-name signatures for assemblies.



        static void Main(string[] args)


            Assembly asm = Assembly.LoadFile(@"PathToFilefileName.exe");




The format of the display name of an AssemblyName is a comma-delimited Unicode string that begins with the name, as follows:

Name <,Culture = CultureInfo> <,Version = Major.Minor.Build.Revision> <, StrongName> <,PublicKeyToken> ”

Name is the textual name of the assembly. CultureInfo is the RFC1766-format-defined culture. Major, Minor, Build, and Revision are the major version, minor version, build number, and revision number of the assembly. StrongName is the hexadecimal-encoded low-order 64 bits of the hash value of the public key generated using the SHA-1 hashing algorithm and the public key specified by SetPublicKey. PublicKeyToken is the hexadecimal-encoded public key specified by SetPublicKey.

Hexadecimal encoding is defined as the conversion of each byte of a binary object to two hexadecimal characters, progressing from least to most significant byte. Additional display values will be added as deemed necessary.

If the full public key is known, then PublicKey may be substituted for StrongName.

Also note that except for Name, which must come first, the lexical order of parameters is unimportant. However, any parameter (Version, Culture, StrongName or PublicKey) not specifically set is considered to be omitted, and the AssemblyName is then considered partial. When specifying partial information, Name parameters must be specified in the order described above.

When supplying a display name, the convention StrongName =null or PublicKey= null indicates that binding and matching against a simply named assembly is required. Additionally, the convention Culture= "" (double quote representing an empty string) indicates matching against the default culture.
