How to modify Windows System Registry Values with C#? As usual, you need to use Microsoft.Win32 Namespace ~ using Microsoft.Win32;. Let’s take Windows Application Event Logs values as an example. I want to change the MaxSize and Retention values in Application Event Log file by using C#.

Codes to change Windows System Registry values

RegistryKey TestEventLog = Registry.LocalMachine.OpenSubKey(“System\\CurrentControlSet\\Services\\EventLog\\Application”,true);
TestEventLog.SetValue(“MaxSize”, “102367232″, RegistryValueKind.DWord);
TestEventLog.SetValue(“Retention”, “0″, RegistryValueKind.DWord);

Above codes open Application event log and with write permission (,true). It changes both MaxSize and Retention values.
Just change the codes to suit your need.

How to read and write Windows System Registry Keys and Values? I need to create a value at Windows System Registry for my project lately. It is used for SCOM discovery. I need a Windows System Registry key to determine that the server is the server that SCOM going to monitor.

First thing to do in your C#. Add using Microsoft.Win32; RegistryKey and Registry requires Microsoft.Win32 as the assembly reference.

Here are the codes that write Windows System Registry Keys.

RegistryKey JayceOoiKey = Registry.LocalMachine.CreateSubKey(“SOFTWARE\\JayceOoi”);

This will create key JayceOoi under HKEY_LOCAL_MACHINE\SOFTWARE\.

To read Test string value from HKEY_LOCAL_MACHINE\SOFTWARE\JayceOoi\

string Output = JayceOoiKey.GetValue(“Test”);

These are the methods that I use to read and write Windows System Registry Keys and Values. Hope it will help in your programming work.
