ProcessModule Class

Represents a.dll or .exe file that is loaded into a particular process.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public class ProcessModule : Component
public class ProcessModule extends Component
public class ProcessModule extends Component
Not applicable.

A module is an executable file or a dynamic link library (DLL). Each process consists of one or more modules. You can use this class to get information about the module.

The following code sample demonstrates how to use the ProcessModule class to get and display information about all the modules that are used by the Notepad.exe application.

Process myProcess = new Process();
// Get the process start information of notepad.
ProcessStartInfo  myProcessStartInfo = new ProcessStartInfo("notepad.exe");
// Assign 'StartInfo' of notepad to 'StartInfo' of 'myProcess' object.
myProcess.StartInfo = myProcessStartInfo;
// Create a notepad.
ProcessModule myProcessModule;
// Get all the modules associated with 'myProcess'.
ProcessModuleCollection myProcessModuleCollection = myProcess.Modules;
Console.WriteLine("Properties of the modules  associated "
   +"with 'notepad' are:");
// Display the properties of each of the modules.
for( int i=0;i<myProcessModuleCollection.Count;i++)
   myProcessModule = myProcessModuleCollection[i];
   Console.WriteLine("The moduleName is "
   Console.WriteLine("The " +myProcessModule.ModuleName + "'s base address is: "
   Console.WriteLine("The " +myProcessModule.ModuleName + "'s Entry point address is: "
   Console.WriteLine("The " +myProcessModule.ModuleName + "'s File name is: "
// Get the main module associated with 'myProcess'.
myProcessModule = myProcess.MainModule;
// Display the properties of the main module.
Console.WriteLine("The process's main moduleName is:  "
Console.WriteLine("The process's main module's base address is: "
Console.WriteLine("The process's main module's Entry point address is: "
Console.WriteLine("The process's main module's File name is: "
