用stream的地方，最好修改为
using(FileStream stream = new FileStream(@"D:\1.Soap", FileMode.Open, FileAccess.Read))
{
.........
}
代码简洁，还不容易出错。
是不是这样的话就不用
stream.Flush();133
stream.Close();134
stream.Dispose();
这三句了，能不能在稍微解释一下
@27080501:using块的作用是：结束时调用对应的dispose()方法。对于你的例子，相对于stream.Close();stream.Dispose(); 这两条语句。其实你的代码没有必要加stream.Close();这句，stream.Dispose(); 这句就够了。

上面确实可以简洁。

128 FileStream stream = new FileStream(@"D:\1.Soap", FileMode.Open, FileAccess.Read);
129 SoapFormatter soapformatter = new SoapFormatter();
130 Student stu=(Student )soapformatter.Deserialize(stream);
131 return (stu); //好像这样return的太早了吧
132 stream.Flush();
133 stream.Close();
134 stream.Dispose();
哦，是renturn的有些早了，应该放到最后，谢谢

public int Stu_Id;
28 public string Stu_Name;
29 public string Stu_Sex;
30 public int Stu_Age;
我觉得这些字段的访问性可以弄成 private
然后利用 属性来访问
private string stu_Name; //变量名开头小写
public string Stu_Name
{
get
{
return stu_Name;
}
set
{
stu_Name=value;
}}
还有就是代码注释写详细一些
路过，不错的
.NET 本身提供的机制就让我们写代码很容易
