使用:ASP .NET MVC 4在我的一个页面中我需要一个具有一定宽度和高度的textarea使用html helper类.我的一些代码如下:

    <div class="editor-label">
        @Html.LabelFor(model => model.MailSubject)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.MailSubject)
        @Html.ValidationMessageFor(model => model.MailSubject)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.MailBody)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.MailBody)
        @Html.ValidationMessageFor(model => model.MailBody)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Content)
    </div>
    <div class="editor-field1">
        @Html.EditorFor(model => model.Content)
        @Html.ValidationMessageFor(model => model.Content)
    </div>

我想知道如何定义editorfor(model.content)的大小(宽度/隐藏)？

我有这个页面从html表单插入数据.没有显示错误,但也没有插入数据.这是给出的代码.

<?php 
mysql_connect("localhost","root","");
mysql_select_db("hcp");

$queryUserType = "select * from user_type";
$resultUserType = mysql_query($queryUserType) or die(mysql_error());

$queryTitle = "select * from name_titles";
$resultTitle = mysql_query($queryTitle) or die(mysql_error());

$time = time();
$date = date("d-m-y");
$nowDateTime=$time.$date;

if($_REQUEST['btnUserSubmit'])
{
    $queryInsertUser="INSERT INTO  users (`title_id`, `first_name`, `last_name`, `email`, `utid`, `residence_address1`, `residence_address2`, `residence_city`, `residence_state`, `residence_country`, `residence_zipcode`, `phone_no`, `username`, `password`, `created`, `date_of_birth`, `gender` ) VALUES ('".mysql_real_escape_string($_REQUEST['$rowTitle[0]'])."', '".mysql_real_escape_string($_REQUEST['txtFirstName'])."', '".mysql_real_escape_string($_REQUEST['txtLastName'])."', '".mysql_real_escape_string($_REQUEST['txtEmail'])."', '".mysql_real_escape_string($_REQUEST['rowUserType[0]'])."', '".mysql_real_escape_string($_REQUEST['txtAddressLine1'])."', '".mysql_real_escape_string($_REQUEST['txtAddressLine2'])."', '".mysql_real_escape_string($_REQUEST['txtCity'])."', '" .mysql_real_escape_string($_REQUEST['txtState'])."', '".mysql_real_escape_string($_REQUEST['txtCountry'])."', '".mysql_real_escape_string($_REQUEST['txtPhone'])."', '".mysql_real_escape_string($_REQUEST['txtUserName'])."', '".mysql_real_escape_string($_REQUEST['txtUserPassword'])."', '".$nowDateTime."', '".mysql_real_escape_string($_REQUEST['txtdateofbirth'])."', '".mysql_real_escape_string($_REQUEST['rdGender'])."');";

$resultinsert=mysql_query($queryInsertUser) or die(mysql_error());
}
?>

我没有任何问题,页面重定向.表单验证仍然存在.在此表中,只有email,utid,username,password这四个字段都是NOT …

我有一个字符串:

SELECT Sparte_id,Registernummer,Gesellschaft_ID,pk_id,Gesellschaft_Name,gesellschaft_crm,

现在我想从字符串中删除最后一个(逗号).最后一个逗号后面有一个,两个或三个空格.

我想删除最后几封信.我怎么能这样做？

在npm run build时间显示的错误

我们已经使用JavaScript / jQuery以编程方式轻松触发了按键/按下/按下事件。

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

但是，使用Angular 5和TypeScript，我们该怎么做呢？

//I am setting value programmatically -> working
document.getElementById('custom_Credit').setAttribute('value', coinsToBuy);    
//setting focus -> working
document.getElementById('custom_Credit').focus();
//but there are no way to generate or trigger keypress/up events.
document.getElementById('custom_Credit')..........;

我想创建一个自定义查询生成器，它将支持CRUD操作。我正在使用c＃、. Net 4.0 SQL Server2008。但是我不知道从哪里开始。我不会使用任何DLL或API。但是您可以参考我可以获取主题的任何开源文件，该主题我想要构建以及如何构建。

可能的重复：
从 C# 中的路径字符串获取文件名

使用：c# asp.net vs10

假设， filepath = "C:\Sys\Axa_Excel\Axa123.xlsx"。文件路径是一个字符串变量。文件可以来自任何位置。但文件将始终为 xls/xlsx/csv。我如何只从只是一个字符串的文件路径中获取文件名？
