Hi I have following loop. With one of the workflow, rangeDataMappingsToClear gets 100,000 records and rangeKeyMappings gets 10,000 records. This is taking long time hence application hangs. How to simplify this loop?

List rangeDataMappingsToClear= new List();
Dictionary<string, object> rangeDataMappings = new Dictionary<string, object>();
Dictionary<string, List<string>> rangeKeyMappings = new Dictionary<string, List<string>>();

foreach (string key in rangeDataMappingsToClear)
{
rangeDataMappings.Remove(key);
foreach (List<string> formulaKeys in rangeKeyMappings.Values)
{
while (formulaKeys.Remove(key)) { }
}
}
rangeDataMappingsToClear.Clear();
