How do I know if my assembly is launched within SQL Server CLR environment?

I need to use the same dll in my Asp.Net project and in SQL CLR. When my assembly is launched by Asp.Net project my dll uses config-file to get settings. Being launched inside SQL Clr my assembly should get settings from special config-table. I don't know how to find out, from where to get settings without catching exceptions. Is there any better way to know that dll was launched within SQL CLR?

C#

try
{
     //Check for Clr-specific connection
     using (SqlConnection connection = new SqlConnection("context connection=true"))
     {
         return "get settings from sql table";        
     }
}
catch (Exception ex)
{
    return "get settings from config-file";
}

Use the SqlContext.IsAvailable property[^]:

C#

if (Microsoft.SqlServer.Server.SqlContext.IsAvailable)
{
    // Load the settings from the SQL table
}
else
{
    // Load the settings from the config file
}

Thank you for your help. It's working.) I really have to look through the Microsoft.SqlServer.Server namespace more carefully.
