The method of judging whether a file or a file exists in C#

A few days ago, when I was looking for a method to determine whether a file exists, I stepped on a few pits and found two methods, File.Exists() and Directory.Exists() (both refer to the System.IO namespace). These two methods are easy confused. The difference in usage is as follows:

1. File.Exists()

if(File.Exists(path+".文件后缀名"))	//该方法是判断该路径下有没有该文件，注意一定要加上文件后缀名
{
    
    
}
else
{
    
    
	FileStream fs = File.Create(path);//创建文件
	fs.Close();
	fs.Dispose();
	return ;	
}

2. Directory.Exists()

if(Directory.Exists(path))	//该方法是判断该路径下有没有该文件夹，注意并不能判断某个文件是否存在
{
    
    
}
else//如果不存在
{
    
    
	Directory.CreateDirectory(path);//创建这个文件夹
}
