C # Methods for obtaining information about program Files

This article describes the C # get program file related information method, share for everyone for your reference.

The implementation method is as follows:

Using system.reflection;using system.runtime.compilerservices;////general information about assemblies is controlled by the following//property set. Change these property values to modify the information associated with the assembly//. [Assembly:assemblytitle ("")][assembly:assemblydescription ("")][assembly:assemblyconfiguration ("")][assembly: Assemblycompany ("")][assembly:assemblyproduct ("")][assembly:assemblycopyright ("")][assembly:assemblytrademark ( "") The version information for the][assembly:assemblyculture ("")]////assembly consists of the following 4 values:////major Version//minor version//build number//revision number////You can specify all these values, or you can use the revision number and the The default value of the build number, by using ' * ' as follows//: [Assembly:assemblyversion ("1.0.*")]////to sign the assembly, you must specify the key to use. For more information about assembly signing, see the//Microsoft. NET Framework documentation. Use the following properties to control the key used for signing. Note://(*) If no key is specified, the assembly is not signed. (*) KeyName refers to a key that is already installed on the computer///cryptographic service Provider (CSP). KeyFile refers to a file that contains//keys. (*) If both the KeyFile and KeyName values are specified, the following processing occurs://(1) If the KeyName can be found in the CSP, the key is used. (2) If the KeyName does not exist and the keyfile exists, the key in the//keyfile is installed in the CSP and uses the key. (*) To create keyfile, you can use the Sn.exe (strong name) utility. When specifying KeyFile, the location of the keyfile should be relative to//project output directory, i.e.//%project directory%obj<configuration>. For exampleIf KeyFile is located in//the project directory, the assemblykeyfile//property should be specified as [Assembly:assemblykeyfile (": \.. \mykey.snk ")]//(*) delay signature is an advanced option-for more information about it, see the Microsoft. NET framework//documentation. [Assembly:assemblydelaysign (False)][assembly:assemblykeyfile ("")][assembly:assemblykeyname ("")]
