我使用DataTable和有关用户的信息,我希望在此DataTable中搜索用户或用户列表.我试试但是不起作用:(
这是我的c#代码:
public DataTable GetEntriesBySearch(string username,string location,DataTable table)
{
list = null;
list = table;
string expression;
string sortOrder;
expression = "Nachname = 'test'";
sortOrder = "nachname DESC";
DataRow[] rows = list.Select(expression, sortOrder);
list = null; // for testing
list = new DataTable(); // for testing
foreach (DataRow row in rows)
{
list.ImportRow(row);
}
return list;
}
您好我如何使用linq过滤数据表到数据表？我有一个DropDownList,我可以选择模块列的值.现在我想用这个模块列过滤DataTable.
这是我的数据表结构:
User | Host | TimeDiff | License | Telefon | Modul
这里的代码:
protected void drp_Modules_SelectedIndexChanged(object sender, EventArgs e)
{
string value = drp_Modules.SelectedValue;
DataTable tb = (DataTable)Session["dt_Users"];
tb = from item in tb //?????
LoadUsertable(tb);
}
嗨,我想在我的DataTable中搜索行,我试试这个:
protected void imggastsuche_Click(object sender, EventArgs e)
{
string searchstring = txtgastsuche.Text;
DataTable tb = DataBaseManager.GetDataTable(mysqlconnectionstring);
DataRow[] foundRows = tb.Select("FIRSTNAME,LASTNAME,NAME,COMPANY,TIMEFROM,TIMETO,CREATOR Like '%" + searchstring + "%'");
tb = foundRows.CopyToDataTable();
this.ListView.DataSource = tb;
this.ListView.DataBind();
}
但我的字符串中有错误.如果我想搜索此列,我该怎么办？
嗨我对c#和批处理文件有疑问.我想执行批处理命令并将输出保存在c#中的字符串中.但我只能执行该文件,但不能将此内容保存在字符串中,并在文本框中显示.
我的批处理文件:
@echo关闭
"C:\ lmxendutil.exe"-licstatxml -host serv005 -port 6200> C:\ Temp\HW_Lic_XML.xml notepad C:\ Temp\HW_Lic_XML.xml
这是我的c#代码:
private void btnShowLicstate_Click(object sender, EventArgs e)
{
string command = "'C:\\lmxendutil.exe' -licstatxml -host lwserv005 -port 6200";
txtOutput.Text = ExecuteCommand(command);
}
static string ExecuteCommand(string command)
{
int exitCode;
ProcessStartInfo processInfo;
Process process;
processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;
// *** Redirect the output ***
processInfo.RedirectStandardError = true;
processInfo.RedirectStandardOutput = true;
process = Process.Start(processInfo);
process.WaitForExit();
// *** Read the …在我的ASP.NET应用程序中,我从Active Directory获取信息.我必须使用GUID信息获取有关用户的信息(例如:a28a6a34dsfdsf57d9e54f945a241),但我不知道如何使用右侧过滤器进行此搜索:/
例如,如果我搜索用户姓氏:
DirectoryEntry Entry = new DirectoryEntry("LDAP://" + "Domain");
string filter = "(&(objectClass=user)(objectCategory=person)(cn=" + txtBenutzer.Text + "*))";
DirectorySearcher Searcher = new DirectorySearcher(Entry, filter);
var q = from s in Searcher.FindAll().OfType<SearchResult>()
select new
{
//GetProperty(s, "objectGUID"),
Benutzer = GetProperty(s, "sAMAccountName"),
eMail = GetProperty(s, "mail"),
Vorname = GetProperty(s, "givenName"),
Nachname = GetProperty(s, "sn"),
Telefon = GetProperty(s, "telephoneNumber"),
UserID = s.GetDirectoryEntry().NativeGuid
};
this.myListView.DataSource = q;
this.myListView.DataBind();
现在我需要一个带GUID的过滤器,我可以在AD中找到唯一的用户.此搜索的GUID我有一个字符串UserID = Session ["UserID"].toString()

我想从用户获取Active Directory属性,我想使用System.DirectoryServices.AccountManagement.
我的代码:
public static void GetUserProperties(string dc,string user)
{
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, dc);
UserPrincipal u = UserPrincipal.FindByIdentity(ctx, user);
string firstname = u.GivenName;
string lastname = u.Surname;
string email = u.EmailAddress;
string telephone = u.VoiceTelephoneNumber;
...//how I can get company and other properties?
}
我有一个问题DataTable.我DataTable从数据库中检索一个,其中一列包含1或0.现在我只想检索该列中值为1的行.
列的名称是ACTIVATE.
这是我的DataTable:
DataTable table = new DataTable(TABLE);
//How can I filter here so ACTIVATE == 1?
adapter.Fill(table);
connection.Open();
selectcommand.ExecuteReader();
return table;
我有一个带有ListView的ASP.NET应用程序.在ListView的每一行中,我都有一个LinkButton,它打开一个新的webform"Benutzer.aspx".我的问题是我没有得到这一行的索引.我使用ItemCommand事件,但它不起作用:(
在这里我的代码:
ASPX:
...
<ItemTemplate>
<tr runat="server">
<td align="left" ><asp:Label ID="Label1" Text='<%# Eval("Benutzer") %>' runat="server" /></td>
<td align="left"><asp:Label ID="Label2" Text='<%# Eval("eMail") %>' runat="server" /></td>
<td align="left"><asp:Label ID="Label3" Text='<%# Eval("Vorname") %>' runat="server" /></td>
<td align="left"><asp:Label ID="Label4" Text='<%# Eval("Nachname") %>' runat="server" /></td>
<td align="left"><asp:Label ID="Label5" Text='<%# Eval("Telefon") %>' runat="server" /></td>
<td align="left"><asp:LinkButton runat="server" Text="Anzeigen" CommandName="Anzeigen" OnCommand="ListView1_ItemCommand" CommandArgument="myArguments"></asp:LinkButton></td>
</tr>
</ItemTemplate>
...
cs文件:
...
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "Anzeigen")
{
Label lbText = (Label)e.Item.FindControl("Label2");
string email = lbText.Text; …我有一个ASP.NET应用程序和一个MySQL数据库.我想编写一个类来插入,删除和显示数据库中的数据.我有一个数据库连接,但我无法在数据库中插入数据.
我的类插入方法:
public string CreateEntry(string Connectionstring, string mitarbeiter)
{
connection = new MySqlConnection(Connectionstring);
try
{
var command = connection.CreateCommand();
command.CommandText = "INSERT INTO tb_mitarbeiter (Vorname) VALUES ('tom')";
connection.Open();
return "Mitarbeiter wurde angelegt";
}
catch (Exception ex)
{
return ex.Message;
}
finally
{
connection.Close();
}
}
这Connectionstring是对的.我没有收到错误,但数据库中没有数据.
我的tablename:tb_mitarbeiter列:ID和Vorname
