Hello Apurva

With the following call, you can get a full definition of the protocol. This allows you to collect all table information.

var protocolInfo = engine.GetProtocolInfo(protocolName)    Method not available.

var protocolInfo = engine.GetUserConnection().GetProtocol(protocolName)

You can find the table parameters by looking for the correct parameter under the following property by either the table ID…

var tableParamInfoById = protocolInfo.Parameters.FirstOrDefault(param => param.ID == requestedTableId)

…or the name of the table

var tableParamInfoByDescription = protocolInfo.Parameters.FirstOrDefault(param => param.Description == requestedTableName)

Once you have the correct table parameter you can get all related column with

var columnParameters = tableParamInfo.TableColumnDefinitions;

This will allow you to find the parameter ID of each column, which you can then use again to find each param under protocolInfo.Parameters, in case you need additional info for that parameter, such as the description.

NOTE: Retrieving the protocol information is a big request on the system, so it is not advised to repeatedly do this. In case the automation script you mentioned will be executed very frequently, I would advise to implement additional caching to save previous results, instead of requesting it each time, otherwise performance issues might occur.

Caching can be done by using a static class, using a lock to avoid issues.

internal static class ProtocolInfoCache
{
private static readonly IDictionary<string, GetProtocolInfoResponseMessage> Cache = new ConcurrentDictionary<string, GetProtocolInfoResponseMessage>();

private static readonly object CacheLock = new object();

public static GetProtocolInfoResponseMessage GetCacheProtocol(IEngine engine, string name, string version)
{
lock (CacheLock)
{
string cacheKey = GetCacheKey(name, version);
if (Cache.ContainsKey(cacheKey))
{
return Cache[cacheKey];
}

return GetProtocolInfoFromDataMiner(engine, name, version);
}
}

private static string GetCacheKey(string name, string version)
{
return String.Join(“.”, name, version);
}

private static GetProtocolInfoResponseMessage GetProtocolInfoFromDataMiner(IEngine engine, string name, string version)
{
GetProtocolInfoResponseMessage response = engine.GetUserConnection().GetProtocol(name, version);
Cache.Add(new KeyValuePair<string, GetProtocolInfoResponseMessage>(GetCacheKey(name, version), response));
return response;
}
}
