u实验步骤（4）：
向FileOption.cs文件中添加代码如下：
//==============================第二部分：类设计============================
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace FileOptionApplication
{
class MyFileOption
{
/// <summary>
public bool WriteTextFile(string filepath, string filecontent, Int16 WriteMethord)
{
bool i = true;
try
{
if (WriteMethord == 0)
{
FileStream textfile = File.Open(filepath, FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(textfile, Encoding.Default);
sw.Write(filecontent);
i = true;
sw.Close();
textfile.Close();
}
else if (WriteMethord == 1)
{
FileStream textfile = File.Open(filepath, FileMode.Append, FileAccess.Write);
StreamWriter sw = new StreamWriter(textfile, Encoding.Default);
sw.Write(filecontent);
i = true;
sw.Close();
textfile.Close();
}
else if (WriteMethord == 2)
{
FileStream textfile = File.Open(filepath, FileMode.Create, FileAccess.Write);
StreamWriter sw = new StreamWriter(textfile, Encoding.Default);
sw.Write(filecontent);
i = true;
sw.Close();
textfile.Close();
}
return i;
}
catch
{
i = false;
return i;
}
}
/// <summary>
public bool DiskFileOption(string SourcePath, string TargetPath, Int16 OptionMethord)
{
bool i = true;
try
{
if (OptionMethord == 0)
{
//文件创建
FileStream textfile = File.Create(SourcePath);
textfile.Close();
}
else if (OptionMethord == 1)
{
//文件删除
File.Delete(SourcePath);
}
else if (OptionMethord == 2)
{
//文件复制
File.Copy(SourcePath, TargetPath, true);
}
else if (OptionMethord == 3)
{
//文件移动
File.Move(SourcePath,TargetPath);
}
return i;
}
catch
{
i = false;
return i;
}
}
....（未完待续）
