但是图像不是垂直居中的.如何让它成为中心？
我正在使用window.devicePixelRatio,它可以在Andriod和Iphone上运行,但在IE 10 Windows Mobile中不起作用.任何替代？
我有以下Split功能，
ALTER FUNCTION [dbo].[Split](@String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000))
as
begin
set @String = RTRIM(LTRIM(@String))
declare @idx int
declare @slice varchar(8000)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
我写的时候
SELECT Items …我正在使用RazorEngine.我有一些动态模板,我将在运行时与视图模型绑定.我的要求是在沙箱中运行代码.因此,只允许绑定.RazorEngine允许我在任意app-domain中运行代码,
using (var service = new IsolatedTemplateService(() => appDomain))
{
return service.Parse(newTemplate, model, null, null);
}
如果我使用以下权限运行app-domain,那么它可以工作,
var permissionSet = new PermissionSet(PermissionState.Unrestricted);
但如果我使用这些权限运行它,
var permissionSet = new PermissionSet(PermissionState.None);
permissionSet.AddPermission(new SecurityPermission(PermissionState.Unrestricted));
permissionSet.AddPermission(new ReflectionPermission(PermissionState.Unrestricted));
我会得到,
[SecurityException: Request failed.]

我需要授予特殊许可吗？
我的后台进程是批量更新/插入数据.我需要在临时表中存储一些数据供以后使用.我有5个临时表.如果我使用临时表(CREATE TABLE #T),则需要2-3秒,但如果我使用表变量(DECLARE @T TABLE)则需要超过90秒.这是一个示例临时表,
CREATE TABLE #TempAttributes
(
AID int
,PID int
,ATypeValue nvarchar(MAX)
,ATypeKey nvarchar(MAX)
,PLanguageID int
);
为什么表变量很慢？
我有5到6个项目.项目A和B通过链接文件使用相同的文件.现在,如果我在Razor中使用这个类,我会得到的,
The call is ambiguous between the following methods or properties:
因为Razor视图引用了bin中的所有dll.它引用了项目A和B中的同一个类.如何在编译期间告诉Razor使用项目A而不是项目B？
我有以下方法,
public Task SaveFileContentsAsync(string filePath, Stream stream)
{
using (var fileStream = new FileStream(filePath, FileMode.Create))
{
return stream.CopyToAsync(fileStream);
}
}
此方法只是将流保存到磁盘中.我跟这个方法打电话的时候HttpPostedFileBase.InputStream,

public static long GetCurrentUnixTimestampSeconds()
{
var unixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
return (long)(DateTime.UtcNow - unixEpoch).TotalSeconds;
}
我在SQL Server中需要相同的东西.可能吗？
我的elmah日志显示此错误.每次请求都不会发生这种情况.它间歇性地发生.MVC 5.2,Web API 2.2,ASP.NET Identity 2和Azure网站是我的环境.更新:这是我的Startup.cs,
OAuthOptions = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(settings.AccessTokenExpireTimeSpanInMinutes),
Provider = new MyAuthorizationServerProvider(),
RefreshTokenProvider = new MyRefreshTokenProvider()
};
// Web API configuration and services
// Configure Web API to use only bearer token authentication.
GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication();
GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));
app.UseOAuthAuthorizationServer(OAuthOptions);
app.UseOAuthBearerAuthentication(OAuthBearerOptions);
GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication();
GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));
检查此否OWIN身份验证管理器与请求关联但无法正常工作
