磁盘文件显示与上传
读取本地磁盘文件显示所有文件名代码如下：
//ClientDir下载目录
public Hashtable PopulateDirectoryTree(string ServerDir, string ClientDir, string filtFile)
{
FileHashtable.Clear();
DirectoryInfo di = new DirectoryInfo(Server.MapPath(ServerDir));
Files = Directory.GetFiles(di.ToString());
foreach (string fs in Files)
{
if (filtFile != "")
{
if (fs.Trim().Substring(fs.Trim().LastIndexOf(".") + 1).ToUpper() != filtFile)
{
FileHashtable.Add(fs.Trim().Substring(fs.Trim().LastIndexOf("\\") + 1, fs.Trim().LastIndexOf(".") - fs.Trim().LastIndexOf("\\") - 1), fs.Trim().Substring(fs.Trim().LastIndexOf("\\") + 1));
flag = true;
}
}
else
{
FileHashtable.Add(fs.Trim().Substring(fs.Trim().LastIndexOf("\\") + 1, fs.Trim().LastIndexOf(".") - fs.Trim().LastIndexOf("\\") - 1), fs.Trim().Substring(fs.Trim().LastIndexOf("\\") + 1));
flag = true;
}
}
GLZTUL = GetString(FileHashtable, ClientDir);
return FileHashtable;
}
private string GetString(Hashtable ht,string ClientDir)
{
StringBuilder sb = new StringBuilder();
sb.Append("<ul>");
foreach (DictionaryEntry de in ht)
{
sb.Append("<li>");
sb.Append("<a href=\"" + ClientDir + "" + de.Value + "\" target=\"_blank\">" + de.Key + "</a>");
sb.Append("</li>");
}
sb.Append("</ul>");
return sb.ToString();
}
使用方法实例如下：
//PopulateDirectoryTree("0\\省公司", "0/省公司/", "");//广东电网公司线损管理制度
//this.ltglzd.Text = GLZTUL;
//PopulateDirectoryTree("0", "0/", "PDF");//广州供电局线损管理制度
//this.ltgzxs.Text = GLZTUL;
//PopulateDirectoryTree("0", "0/", "DOC");//广州供电局线损四分管理领导小组和工作小组
//this.Literal3.Text = GLZTUL;
//PopulateDirectoryTree("0\\分析制度", "0/分析制度/", "");//广州供电局线损分析管理制度
//this.Literal4.Text = GLZTUL;
//PopulateDirectoryTree("0\\考核办法", "0/考核办法/", "");//广州供电局线损考核办法
//this.Literal5.Text = GLZTUL;
//PopulateDirectoryTree("0\\实施细则", "0/实施细则/", "");//广州供电局线损四分实施细则
//this.Literal6.Text = GLZTUL;
上传文件代码如下：
protected void uploadFile_Click(object sender, EventArgs e)
{
string UpFilePath = string.Empty;
if (fileType.SelectedValue == "0")
{
UpFilePath = Server.MapPath("0\\省公司");
}
else if (fileType.SelectedValue == "1")
{
UpFilePath = Server.MapPath("0");
}
else if (fileType.SelectedValue == "2")
{
UpFilePath = Server.MapPath("0");
}
else if (fileType.SelectedValue == "3")
{
UpFilePath = Server.MapPath("0\\分析制度");
}
else if (fileType.SelectedValue == "4")
{
UpFilePath = Server.MapPath("0\\考核办法");
}
else
{
UpFilePath = Server.MapPath("0\\实施细则");
}
this.UploadFile(UpFilePath);
Bind();
}
private string UploadFile(string UpFilePath)
{
if (!Directory.Exists(UpFilePath))
{
DirectoryInfo dirinfo = Directory.CreateDirectory(UpFilePath);
}
string file_name = "";
try
{
MyUploader.HttpMedia media = new MyUploader.HttpMedia();
media.SetMaxLength(30000);
ArrayList al = new ArrayList();
al.Add("doc");
al.Add("pdf");
al.Add("xls");
al.Add("mdb");
al.Add("txt");
al.Add("ppt");
media.SetFilter(al);
if (media.Upload(UpFilePath))
{
ClientScript.RegisterStartupScript(this.GetType(), "e", "<script>alert('上传成功!')</script>");
}
else
{
ClientScript.RegisterStartupScript(this.GetType(), "e", "<script>alert('上传失败,请检查文件格式!')</script>");
string s = media.ErrorMessages;
}
}
catch (Exception Err)
{
string Message = Err.Message;
}
return file_name;
}
方法二：
private void SaveAttFile()
{
int i;
string vFileName = "";
string vPath ;
System.Web.HttpFileCollection vFiles=System.Web.HttpContext.Current.Request.Files;
System.Web.HttpPostedFile vFile;
vPath = Request.MapPath("attachFiles");
if (!System.IO.Directory.Exists(vPath))
{
System.IO.Directory.CreateDirectory(vPath);
}
vPath = Request.MapPath("attachFiles/" + mYCID);
if (!System.IO.Directory.Exists(vPath))
{
System.IO.Directory.CreateDirectory(vPath);
}
for (i = 0; i < vFiles.Count; i++)
{
vFile = vFiles[i];
if (vFile.FileName == "")
continue;
vFileName=System.IO.Path.GetFileName(vFile.FileName);
vFile.SaveAs(vPath + "\\" + vFileName);
}
if (this.txtFiles.Text != "")
{
string[] vTxtFiles = this.txtFiles.Text.Split(new char[] { '|' });
string[] vSQLS = new string[vTxtFiles.Length + 1];
vPath = "attachFiles/" + mYCID + "/";
vSQLS[0] = "delete from xskh_attachFiles where ycid=" + mYCID;
for (i = 0; i < vTxtFiles.Length; i++)
{
vSQLS[i + 1] = "insert into xskh_attachFiles (ycid,filename) values (" + mYCID + ",'" + vTxtFiles[i] + "')";
mAtFilesHtml += " <span><a target=\"_blank\" href=\"" + vPath + vTxtFiles[i] + "\">" + vTxtFiles[i] + "</a> <a href='javascript:void(0)' onclick=\"DelFile('" + vTxtFiles[i] + "',this)\">删除</a></span>";
}
DbConnect.Instance.ExecSQL(vSQLS);
}
else
{
DbConnect.Instance.ExecSQL("delete from xskh_attachFiles where ycid=" + mYCID, "main");
}
}
