Hi
The link from Nir's reply above seems to have a decent c# example.  What problem are you having getting this to do what you want?

public static void CreateFeature(IFeatureClass featureClass, IPolyline polyline)
{
  // Build the feature.
  IFeature feature = featureClass.CreateFeature();
  feature.Shape = polyline;

  // Apply the appropriate subtype to the feature.
  ISubtypes subtypes = (ISubtypes)featureClass;
  IRowSubtypes rowSubtypes = (IRowSubtypes)feature;
  if (subtypes.HasSubtype)
  {
    // In this example, the value of 3 represents the PVC subtype.
    rowSubtypes.SubtypeCode = 3;
  }

  // Initialize any default values the feature has.
  rowSubtypes.InitDefaultValues();

  // Update the value on a string field that indicates who installed the feature.
  int contractorFieldIndex = featureClass.FindField("CONTRACTOR");
  feature.set_Value(contractorFieldIndex, "K Johnston");

  // Commit the new feature to the geodatabase.
  feature.Store();
}
