仿制药<；T>；不在c#中工作，甚至运行时没有任何错误

我正在使用Silverlight 5（VS2010）创建一个C#web应用程序。首先，我创建了控制台应用程序，因为一切都很好。但当我在web应用程序中这样做时，问题就出现了

即使在web应用程序中，对于特定的数据类型，它也可以正常工作（例如，对于

int

而不是

，它可以正常工作），但当我使用泛型时，它就不起作用了它编译时无错误，但它甚至不调试设置为“切换断点”的区域。最初，GUI是这样的：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.IO;
using System.Text;
using System.Runtime.InteropServices;
using System.Diagnostics;
namespace 
{
    public partial class MainPage: UserControl 
    {
        byte[] fileContent;
        public MainPage() 
        {
            InitializeComponent();
            fileContent = null; //Suppose it already contains binary fileContents
        }
//I press the button in order to call the Huffman class because it's Object declared in it
        public void ButtonClickEvent(object sender, RoutedEventArgs e) 
        {
            MessageBox.Show("check0");

            //Suppose i had stored contents of a file inside "fileContent" , so fileContent below contains
            //contents of a binary file
           //**THE LINE BELOW IS ERROR PRONE**
            Huffman < uint > obj1 = new Huffman < uint > (this, fileContent, BitConverter.ToUInt32);

            //This Object creation creates problem, whereas if i remove generic type (<T>), Then it works fine.
            //If i don't use genrics then i do it like this : Huffman obj1 = new Huffman(this, fileContent); (Whereas <T> in Huffman class is replaced by "int" and it works fine)

            MessageBox.Show("check1"); //This check box is never executed 
        }
    }

    public class Huffman < T > where T: struct,IComparable < T > ,IEquatable < T > 
    {
        public Huffman(MainPage Object, byte[] fileContent, Func < byte[], int, T > converter) 
        {
            MessageBox.Show("check2"); //It never executes          
            length = fileContent.Length;
            size = Marshal.SizeOf(typeof (T));
            byte[] data;
            for (long position = 0; position + size < length; position += size)
            {
                data = fileContent; //This data conatains the filecontents now
                T processingValue = converter(data, 0); 
                {
                    //I do something here with processingValue it could be int16/int32/int64/uin32/uint64 etc.
                }
            }
        }
    }
}  

但是，当控件传递到容易出错的部分时，GUI会像这样突然消失

我保存断点的地方被这个替换了

（请参见最左端）因此，我无法调试以找到问题

解释一下我想做什么：在下面给定的代码中，我有一个二进制文件，存储在数据类型为

byte[]的“fileContents”中。

（我并没有向您透露读取该文件的方法，现在您可以考虑文件内容包含“代码>主页processingValue变量将是泛型（

），我将存储在

“symbol”

（也是

类型）（从二进制文件读取的此符号可能是我在代码中未显示的

short

/

int

/

long

/

UInt32

/

UInt64

等）之一）

我有这样一个场景：

        }

        public void ButtonClickEvent(object sender, RoutedEventArgs e) 
        {
            MessageBox.Show("check0");

            //Suppose i had stored contents of a file inside "fileContent" , so fileContent below contains

            //This Object creation creates problem, whereas if i remove generic type (<T>), Then it works fine.
            //If i don't use genrics then i do it like this : Huffman obj1 = new Huffman(this, fileContent); (Whereas <T> in Huffman class is replaced by "int" and it works fine)

            MessageBox.Show("check1"); //This check box is never executed 
        }
    }

    public class Huffman < T > where T: struct,IComparable < T > ,IEquatable < T > 
    {
        public Huffman(MainPage Object, byte[] fileContent, Func < byte[], int, T > converter) 
        {
            MessageBox.Show("check2"); //It never executes          
            length = fileContent.Length;
            size = Marshal.SizeOf(typeof (T));
            byte[] data;
            for (long position = 0; position + size < length; position += size)
            {
                data = fileContent; //This data conatains the filecontents now
                T processingValue = converter(data, 0); 
                {
                    //I do something here with processingValue it could be int16/int32/int64/uin32/uint64 etc.
                }
            }
        }
    }
}

就我的担保人而言，这个问题是由于哈夫曼构造函数中的位转换器调用函数Func converter造成的问题。我想我需要以其他方式使用Func converter

在你看来，我看不到你的代码有任何错误。在silverlight中，你不能像Console或WinForm App那样调试使用断点进行复制。

您能发送您的解决方案吗？然后我可以查看。

@Zong谢谢您的编辑，还有一个问题，您能告诉我您是如何在其中添加屏幕截图的吗？步骤是什么？（在回答问题之前，这样我就能够高质量地编写问题）@ZongZhengLi谢谢，好的，我以后会处理的。但是你能在代码中找到问题吗，如果可以，请告诉我解决方法，如果可以的话？非常感谢。值得一提的是，你的断点没有设置在合法的行上。（该行没有执行代码）@KirkWoll好的，谢谢你的回复，但是它应该执行Huffman类，即使我已经为它创建了对象，所以它必须调用，但是为什么它不这样做呢？谢谢，我已经添加了这两个代码，请查看编辑部分。将你的解决方案发送到harshanamcrox10@gmail.com.然后我可以查一下这里有什么问题。好的，一个汉克斯大哥……你会得到的5分钟后在你的邮件里。
