显示当前目录下的每个文件的名称

#region 用DirectoryInfo这个类实现查看目录下的每个文件
public void LookDirectoryInfo()
{
string directoryName = @"c:\tem";
DirectoryInfo directoryInfo = new DirectoryInfo(directoryName);

FileInfo[] fileList = null;
if (!directoryInfo.Exists)//如果不存在创建目录
{
directoryInfo.Create();
}
fileList = directoryInfo.GetFiles();
//foreach (FileInfo file in fileList)
//{
// ListBox1.Items.Add(file);
//}
ListBox1.DataSource = fileList;
ListBox1.DataBind();

}
#endregion

创建文件和创建目录一样的，我这里用的实例类DirectoryInfo

#region 用静态类实现
private void LookDirectory()
{
string directoryName = @"c:\tem";
if(!Directory.Exists(directoryName))
{
Directory.CreateDirectory(directoryName);

}
string[] fileList = Directory.GetFiles(directoryName);
ListBox1.DataSource = fileList;
ListBox1.DataBind();
}
#endregion
