) to control proceduresBecause of the large loss of performance, it is best not to use exceptions to control the process.11. Use the ToString method of the value type to avoid boxing operations.Because value type to reference type can cause performance loss, using the ToString method of the value type avoids the performance loss caused by boxing.12, avoid the abuse of reflection, reflection is also a waste of performance of the operationWhen using reflection to invoke a type or trigger method, o
