我试图将图像设置为自定义UIButton的背景.我能够在界面构建器中为"圆角矩形"UIButton设置背景图像,但现在边框已经消失.有没有办法保留边界？此外,我想使边框显示矩形而不是圆角.
IFRAME在IE和FF中都不可见之后的行.请参考下面的代码,让我知道我做错了什么.

我正在编写常用函数来序列化给定对象和List <object>,如下所示
public string SerializeObject(Object pObject)// for given object
{
try
{
String XmlizedString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(pObject));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xs.Serialize(xmlTextWriter, pObject);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
return XmlizedString;
}
catch (Exception e) { System.Console.WriteLine(e); return null; }
}
public string SerializeObject(List<Object> pObject)// for given List<object>
{
try
{
String XmlizedString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(pObject));
XmlTextWriter xmlTextWriter = new …我需要获取XmlNodeList,其中节点名称包含"mystring"
XML
<?xml version="1.0" encoding="utf-8"?>
<root>
<node1>
node1 value
</node1>
<node2_mystring>
node2 value
</node2_mystring>
<node3>
node3 value
</node3>
<node4_mystring>
node 4 value
</node4_mystring>
</root>
期望的输出是
<?xml version="1.0" encoding="utf-8"?>
<root>
<node2_mystring>
node2 value
</node2_mystring>
<node4_mystring>
node 4 value
</node4_mystring>
</root>
我试过类似的东西 XmlNodeList mystringElements = xmlDocument.SelectNodes(@"//*[contains(name,'mystring')]");
但它返回零节点.我应该在XPath查询中放置什么来实现这一目标.
如何将DateTime"Thu Nov 30 19:00:00 EST 2006"转换为"11/30/2006"
我正在使用Visual Studio 2012专业版.我认为在page指令中为AutoEventWireup属性设置"true"与"false"没有任何区别.它一直表现为"true",意思是 - 我设置"false"而不是显式绑定事件,但事件是隐式绑定的.如果我遗失任何东西,请告诉我.
我试图通过在ASP.net网站中使用反射来创建类的实例.类ClassName已定义并位于App_code文件夹中.以下行返回null,可能是错误的.
