如何将string 类型字段转换为datetime类型字段

string time = Convert。ToDateTime(this.Birthday.Text);是否转化正确，为什么这样写？

Answer 1

DateTime time = new DateTime();
if (!DateTime.TyrParse(this.Birthday.Text, out time))
{
throw new Exception("无法转换日期！");
}
//time就是this.Birthday.Text字符转换成的日期类数据

Answer 2

DateTime time = Convert.ToDateTime(this.Birthday.Text);

Answer 3

错了吧
DateTime time = Convert.ToDateTime(this.Birthday.Text);
Birthday是什么？textBox?

Answer 4

this.Birthday.Text=Convent.ToString(time);
DateTime time = Convert.ToDateTime(this.Birthday.Text);
convent.ToDateTime()是转换日期格式的。
convent.ToString()是转换字符串格式
