Using ternary operators in inline Lambda LINQ queries

Let's say you have an Entity Framework query that returns a list of type User. And let's say your search query has multiple potential search filters that you want to apply.

Here's an example of where the "fullLoginName" field could be a full name that you can split on, such as "Clyde Thomes", or it could be a single items such as "Administrator":

if (isFilteredByLastName){	targetUsers = targetUsers.Where(x=>x.fullLoginName.Contains(" ")?x.fullLoginName.Split(' ')[1]==lastName:x.fullLoginName.Contains(lastName)).ToList();}

You can then use the targetUsers result as the subject of the next filter item.

DbCommand cmd = ctx.Database.Connection.CreateCommand();

cmd.CommandText = sql; cmd.CommandType = CommandType.Text;

foreach (DbParameter p in parms) cmd.Parameters.Add(p);

try {


DbDataReader reader = cmd.ExecuteReader();

ObjectResult<T> jInfo = ((IObjectContextAdapter) ctx) .ObjectContext .Translate<T>(reader);

return jInfo.FirstOrDefault();


finally { ctx.Database.Connection.Close();
