i tried this:

string baseValue = System.Configuration.ConfigurationManager.AppSettings["Base_GDL_Matltrans"];
string relVaue = System.Configuration.ConfigurationManager.AppSettings["Relative_GDL_Matltrans"];
searchURL = (string)baseValue.Concat(relVaue);

You should use the Uri Class (System) | Microsoft Docs[^] which allows you to build the URI from the base parts.

Read the documentation, where it is all explained.

Use the Uri.TryCreate method[^]:

C#

Uri baseUri;
string baseValue = System.Configuration.ConfigurationManager.AppSettings["Base_GDL_Matltrans"];
if (!Uri.TryCreate(baseValue, UriKind.RelativeOrAbsolute, out baseUri))
{
    throw new ConfigurationErrorsException("Invalid base URL.");
}

Uri searchUri;
string relVaue = System.Configuration.ConfigurationManager.AppSettings["Relative_GDL_Matltrans"];
if (!Uri.TryCreate(baseUri, relValue, out searchUri))
{
    throw new ConfigurationErrorsException("Invalid relative URL.");
}

searchUrl = searchUri.ToString();

If that doesn't work, you'll need to check the values returned from the <appSettings> section in your web.config file.
