The following sample code will create a folder and a subfolder on your C: drive, and then create a new file in the subfolder with a random file name. Finally, some data will be written to the file. (The code is well-commented, and you should be able to figure out what's going on by studying it carefully.)
以下示例代码将在您的 C: 驱动器上创建一个文件夹和一个子文件夹，然后在该子文件夹中创建一个具有随机文件名的新文件。最后，一些数据将写入文件。（代码有很好的注释，你应该能够通过仔细研究来弄清楚发生了什么。）
public class CreateFileOrFolder
{
static void Main()
{
// Specify a "currently active folder"
string activeDir = @"c:\testdir2";
//Create a new subfolder under the current active folder
string newPath = System.IO.Path.Combine(activeDir, "mySubDir");
// Create the subfolder
System.IO.Directory.CreateDirectory(newPath);
// Create a new file name. This example generates a random string.
string newFileName = System.IO.Path.GetRandomFileName();
// Combine the new file name with the path
newPath = System.IO.Path.Combine(newPath, newFileName);
// Create the file and write to it.
// DANGER: System.IO.File.Create will overwrite the file
// if it already exists. This can occur even with random file names.
if (!System.IO.File.Exists(newPath))
{
using (System.IO.FileStream fs = System.IO.File.Create(newPath))
{
for (byte i = 0; i < 100; i++)
{
fs.WriteByte(i);
}
}
}
// Read data back from the file to prove that the previous code worked.
try
{
byte[] readBuffer = System.IO.File.ReadAllBytes(newPath);
foreach (byte b in readBuffer)
{
Console.WriteLine(b);
}
}
catch (System.IO.IOException e)
{
Console.WriteLine(e.Message);
}
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
