第1.种方法
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
User sz = new User();
sz.SetName( "小王");
sz.SetSex( "牛");
MessageBox.Show("姓名:" + sz.GetName()+"\r\n" + "性别:" + sz.GetSet());
}
}
class User
{
private string m_Name;
private string m_Sex;
public string GetName()
{
return m_Name;
}
public void SetName(string Values)
{
m_Name = Values;
}
public string GetSet()
{
return m_Sex;
}
public void SetSex(string Values)
{
if (Values == "男" || Values == "女")
{
m_Sex = Values;
}
else
{
MessageBox.Show("姓名必须是'男'或‘女’");
}
}
}
第2.种方法（采取使用属性也可以达到同样的效果）
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
User sz = new User();
sz.Name = "小王";
sz.Sex = "谁";
MessageBox.Show("姓名:" + sz.Name + "\r\n" + "性别:" + sz.Sex);
}
}
class User
{
private string m_Name;
private string m_Sex;
public string Name
{
get
{
return m_Name;
}
set
{
m_Name =value;
}
}
public string Sex
{
get
{
return m_Sex;
}
set
{
if (value == "男" || value == "女")
{
m_Sex = value;
}
else
{
MessageBox.Show("姓名必须写'男'或'女'");
}
}
}
}
