我需要删除日期时间的时间部分,或者可能使用以下格式的日期,格式object不是string.
06/26/2009 00:00:00:000
我不能使用任何string转换方法,因为我需要object表单中的日期.
我尝试首先将其转换DateTime为a string,从中删除特定时间的日期,但是12:00:00 AM一旦我将其转换回来,它就会添加DateTime object.
我正试图删除一个小写字母TextBox..
例如,代表保险的短alpha代码(例如,'Blue Cross Blue Shield'的'BCBS'):
txtDesc.text = "Blue Cross Blue Shield";
string Code = //This must be BCBS..
可能吗？请帮我.谢谢!

这是我的C#代码..
SmtpClient SmtpMail = new SmtpClient();
SmtpMail.Host = "localhost"; …我想从GridView中删除记录.在此之前要求确认,例如"你确定要删除吗？"
我在GridView中使用了命令字段,
<asp:CommandField HeaderText="Delete" ShowDeleteButton="True" />
我在javascript中编写了一个函数
function confirm_Delete()
{
var r = confirm("Are you sure you want to Remove this Record!");
if (r == true)
{
alert("Record Deleted");
return true;
}
else
{
return false;
}
}
如何在删除点击时调用此方法.请建议!
是否可以在C#中添加日期？
(DateTime.Today.ToLongDateString() + 10)
我试过这个,但它不起作用.
我有使用问题Split Method().
我有一个像这样的字符串:
string diagnosis = "001.00 00 002.01 00 003.00 01";
输出应该是:
001.00
002.01
003.00
我尝试用这两种方法删除两位数字:
string[] DiagnosisCodesParts = diagnosis.Split();
if (DiagnosisCodesParts[x].Length > 3)
{
//here
}
和..
string DiagnosisCodestemp = diagnosis.Replace(" 00 ", " ").Replace(" 01 ", " ").Replace(" 02 ", " ")
还有其他方法可以删除两位数字吗？
如果值已存在,如何停止循环？
这是我在C#中的代码......
foreach (ArrayList item in ArrData)
{
HCSProvider.NewProviderResult oResult;
oResult = oHCSProvider.CreateNewProvider(providercode, oProviderDetail)
DBInterface ProviderDetail = new DBInterface();
ProviderDetail.InsertProvider(Convert.ToInt64(providercode), Convert.ToString(oProviderDetail));
}
我无法使用Gmail设置发送电子邮件.我已经尝试过client.Host ="localhost"它正在工作但不在client.Host ="smtp.gmail.com"..请帮助我们..我需要使用client.Host ="smtp.gmail.com"..谢谢

string from = "aevalencia119@gmail.com"; //Replace this with your own correct Gmail Address
string to = "aevalencia191@gmail.com"; //Replace this with the Email Address to whom you want to send the mail
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true ; mail.Priority = MailPriority.High;
SmtpClient client = new …我在asp.net中使用了repeater.我的问题是不知道如何隐藏转发器中的字段.有正常价格和现在价格,如果正常价格等于零,它将隐藏字段,如果不是,它将显示正常价格的价值.我希望你能帮忙解决这个问题.
这里是我在asp中的代码:
<a href="<%=Utility.GetSiteRoot() %>/BookInfo.aspx?SKU=<%# Utility.SKUMask(Eval("lb_sku").ToString()) %>">
