小编Gar*_*eth的帖子

我有一个关于在我的xml架构(xsd)中添加限制的问题.我有一个复杂的类型:

<xsd:complexType name="xxx">
   <xsd:attribute/>
   .....
</xsd:complexType>

我在这个复杂类型中有很多属性,其中很少有字符串类型.现在我希望将这些字符串类型属性限制为y no.chars,我该如何添加此限制？

谢谢!-Ankush

我试图将标签的内容绑定到类实例的字符串属性,但没有太大成功.

XAML:

<Window x:Class="WPFBindingTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">    
<Grid>        
    <Label Height="28" Margin="12,55,106,0" Name="label1" Background="Bisque"
           Content="{Binding Source=MyFoo, Path=W1}" VerticalAlignment="Top" />

    <Label Height="28" Margin="12,12,106,0" Name="label2" Background="Bisque"
           Content="{Binding Source=MyFoo, Path=W2}"  VerticalAlignment="Top" />

    <Button Height="23" HorizontalAlignment="Right" Margin="0,0,32,48"
            Name="button1" VerticalAlignment="Bottom" Width="89"
            Click="button1_Click">
        Set Properties
    </Button>

</Grid>   
</Window>

C#:

namespace WPFBindingTest
{
   public partial class Window1 : Window
    {
        public Foo MyFoo;

        public Window1()
        {
            InitializeComponent();            

            MyFoo = new Foo();           
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {      
            MyFoo.W1 = "Hello";
            MyFoo.W2 = "Dave";
        } …

我试图确定派生类的属性值,当它通过基类参数传递给方法时.

例如,下面是完整的代码示例:

class Program
{
    static void Main(string[] args)
    {
        DerivedClass DC = new DerivedClass();
        ProcessMessage(DC);
    }

    private static void ProcessMessage(BaseClass baseClass)
    {
        Console.WriteLine(GetTargetSystemFromAttribute(baseClass));
        Console.ReadLine();
    }

    private static string GetTargetSystemFromAttribute<T>(T msg)
    {
        TargetSystemAttribute TSAttribute = (TargetSystemAttribute)Attribute.GetCustomAttribute(typeof(T), typeof(TargetSystemAttribute));

        if (TSAttribute == null)
            throw new Exception(string.Format("Message type {0} has no TargetSystem attribute and/or the TargetSystemType property was not set.", typeof(T).ToString()));

        return TSAttribute.TargetSystemType;
    }
}

public class BaseClass
{}

[TargetSystem(TargetSystemType="OPSYS")]
public class DerivedClass : BaseClass
{}

[AttributeUsage(AttributeTargets.Class)]
public sealed class TargetSystemAttribute : Attribute …

我想转换一个for循环,它将迭代器的每次递增增加2,使用TPL进入Parallel For循环.数据不依赖于顺序或以任何方式受约束,但我只想处理源数组的每个其他元素中的数据(在下面的代码中是_Datalist),因此需要增加2.

我的For循环:

for (int i = 1; i < _DataList.Length - 1; i += 2)
{
     // Do work for _DataList[i]
}

是否有可能告诉并行循环我想要增加2而不是1？

这是并行循环,但显然我每次迭代只增加1:

        Task.Factory.StartNew(() =>
            Parallel.For(1, _DataList.Length, i =>
            {
                // do work for _DataList[i]                    
            })
        );

我可以告诉内部循环体忽略i的奇数值,但这看起来很麻烦 - 有没有办法在循环初始化中做某种方式？

可能是微不足道的问题..我想实现我自己的错误处理程序来记录错误并监视正在发生的事情.此时我不想向客户提供自己的错误.我希望它是透明的 - 就像默认的WCF行为一样.我应该如何ProvideFault实现这一目标？

namespace IDATT.Web.Services
{
    using System;
    using System.ServiceModel.Channels;
    using System.ServiceModel.Dispatcher;

    public class MyServiceErrorHandler : IErrorHandler 
    {
        public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
        {
            // ????
        }

        public bool HandleError(Exception error)
        {
            return true;
        }
    }
}
