Code snippet to get all installed languages from sharepoint server Farm

I had a requirement to display all installed languages of a SharePoint server farm in a DropDownList.

Regional Settings of SPWeb has a property named "SPWeb.RegionalSettings.InstalledLanguages", which returns language collection of type
"SPLanguageCollection". The following are the properties of "SPLanguage" instance.




Use the "Display Name" property to get the language display name ex. English and "LCID" property to get the locale ID ex. 1033(for English).
See the below code snippet, which will be used to get the installed languages from a SharePoint server farm.

Registering Assembly to GAC via Code

Registering Assembly to GAC via Code

As we know to register an assembly toGlobal Assembly Cache, the assembly must be strong named. This strong name is used to prevent spoofing of your code. Use the “gacutil.exe” to install the assembly to the GAC.

Example

gacutil /i MyAssembly.dll

The above command will installs the “MyAssembly.dll” in to the GAC.
See the following code snippet to do the above stuff by C# code.

try
{
string assemblyName = “MyAssembly.dll”;

ProcessStartInfo pStartInfo = new ProcessStartInfo();

//specify gacutil.exe whith which to start the process
pStartInfo.FileName = "gacutil.exe";
pStartInfo.Arguments = string.Format("/i {0}", assemblyName);
pStartInfo.UseShellExecute = false;

//start the process
Process process = Process.Start(pStartInfo);

//wait till the process completes
process.WaitForExit();
}
catch (Exception e)
{
MessageBox.Show(string.Format("Error registering the assembly :
'{0}'.\n{1}", assemblyName, e.Message),
"GAC Installation Error");
}

The “UseShellExecute” property indicates whether to use the operating system shell to start the process. The default is “true”. Set this property to “false” – The process is created directly from the executable file.
