tVers = context.MCurrentVer

  .ToDictionary(k => k.TName, 
                v => v.CVer);

Answer 1

Use !category.Contains(x.TName) to filter out x.TName that are in the catrgory list.

tVers = context.MCurrentVer
   .Where(x => x.MKey == 1000 && !category.Contains(x.TName))
   .ToDictionary(k => k.TName, v => v.CVer);
