JoinType joinType = JoinType.InnerJoin; string joinString = joinType.GetJoinString(); // output: "INNER JOIN"
JoinType joinType = JoinType.LeftJoin; string joinString = joinType.GetJoinString(); // output: "LEFT JOIN"In this example, the JoinType enum value is set to LeftJoin, and the GetJoinString method is called to return the SQL JOIN string "LEFT JOIN". The JoinType class is not a built-in C# class, and thus it is likely a part of a third-party library or package. The exact package or library would need to be determined based on the context in which the JoinType class is being used.
