{
DataTable dt = new DataTable();
DataColumn dcname = new DataColumn("文件名称");
DataColumn dcsize = new DataColumn("文件大小");
DataColumn dctype = new DataColumn("文件类型");
DataColumn dcdate = new DataColumn("修改日期");
dt.Columns.Add(dcname);
dt.Columns.Add(dcsize);
dt.Columns.Add(dctype);
dt.Columns.Add(dcdate);
string path = "文件路径";
if (Directory.Exists(path))
{
string[] filelist = Directory.GetFiles(path);
foreach (string file in filelist)
{
DataRow dr = dt.NewRow();
FileInfo fileInfo = new FileInfo(file);
dr["文件名称"] = fileInfo.Name;
dr["文件大小"] = fileInfo.Length;
dr["文件类型"] = fileInfo.Extension;
dr["修改日期"] = fileInfo.LastWriteTimeUtc;
fileInfo = null;
dt.Rows.Add(dr);
}
}
return dt;
}
public void DataBindingFiles()
{
this.dataGridView1.DataSource = CreateTable();
}
this.DataBindingFiles();这是我列文件的代码,我现在用的本地目录代替。还没列FTP上的现在本地文件是能显示,把文件路径换成FTP上的,是不是就能显示FTP上的文件???我还没测试,我是新手,不大懂啊

帮帮忙啊
代码是封装好的Ftp操作的类
class FtpUpDown 构造时 设好IP地址,用户名,和密码
public FtpUpDown(string ftpServerIP, string ftpUserID, string ftpPassword) 调用这个函数就可惜获取文件名列表
