一、显示类型转换：
Dictionary<string,object> dict = new Dictionary<string,object>();
dict.Add("Id", "111");
dict.Add("Name", "NAMSDJFIDSJF");
dict.Add("Genger", true);
try
{
var person = (Person)(object)dict;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
输出结果：
二、as转换：
Dictionary<string,object> dict = new Dictionary<string,object>();
dict.Add("Id", "111");
dict.Add("Name", "NAMSDJFIDSJF");
dict.Add("Genger", true);
try
{
var person = (object)dict as Person;
Console.WriteLine(person);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
输出结果：
三、结论
- 显示类型转换失败是直接抛出异常;
- as转换转换失败是返回null.
