问题描述

班级计划
{
静态void Main(string [] args)
{
bool fileExists = false;

字符串thePath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

字符串thefile = thePath + @"\ y.txt;

fileExists = File.Exists(thefile);

如果(fileExists)
{
Console.WriteLine(文件存在");

}
其他
{
Console.WriteLine(文件不存在，正在创建");
File.Create(thefile);



}


如果(fileExists)
{
字符串newpath = Environment.GetFolderPath(Environment.SpecialFolder.MyComputer);
字符串newfile = newpath + @"\ newlife.text";
Console.WriteLine(它是在{0}上创建的"，File.GetCreationTime(thefile));
Console.WriteLine(上次在{0}上访问"，File.GetLastAccessTime(thefile));
Console.WriteLine(正在移动文件...");
File.Move(thePath，newpath); //为什么我在此行中有错误??
}

Console.ReadLine();
}

}

class Program

if (fileExists)
{
Console.WriteLine("The file exists");

}
else
{
Console.WriteLine("The file does not exist,creating it");
File.Create(thefile);



}


if (fileExists)

string newfile = newpath + @"\newlife.text";
Console.WriteLine("It was created on {0}",File.GetCreationTime(thefile));
Console.WriteLine("It was last acessed on {0}",File.GetLastAccessTime(thefile));
Console.WriteLine("Moving the file...");
File.Move(thePath,newpath); // why i have error in this line???
}

Console.ReadLine();

推荐答案

您计算出的文件名为thefile，但是您在对File.Move的调用中使用了thePath.始终使用调试器.该代码看起来非常蓬松，不准确和多余.为什么要在一个地方创建文件并使它们移动.通常，硬编码的文件名没有用，但是您使用的是正确的东西，例如Environment.SpecialFolder.您需要更彻底地计划代码，并使其模式组合起来.

Your calculated file name is thefile, but you are using thePath in the call to File.Move. Always use the debugger. The code looks very fluffy, inaccurate and redundant. Why creating a file in one place and them moving. Generally, hard-coded file names are not useful, but you are using right things, such as Environment.SpecialFolder. You need to plan the code more thoroughly and make it mode combed…

我认为您的问题在这条线上

I think Your problem is on this line

string newpath = Environment.GetFolderPath (Environment.SpecialFolder.MyComputer);

我的电脑文件夹.

MyComputer常量始终产生空字符串(")，因为没有为我的电脑"文件夹定义任何路径.

请参考以下链接..

The My Computer folder.

The MyComputer constant always yields the empty string ("") because no path is defined for the My Computer folder.
