列表数组的字典 [英] Dictionary for list array

问题描述

我想为数组列表制作字典我读取他的文本文件元素为双数组

这是我的代码，但我有错误，无法解决它。请帮忙 。

I want to make dictionary for array list i read his element for text file as array of double
this is my code but i have error and can't solve it. help please .

Dictionary<[]double , string> x = new Dictionary<[]double , string>();
 Dictionary<[]double , string> y = new Dictionary<[]double , string>();
            x.add= (File.ReadAllLines(@"E:\TestFile.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"x array");
            y.add = (File.ReadAllLines(@"E:\TestFile2.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"y array");

推荐答案

两个问题：

1）在C＃中，一个双精度数组被声明为 double [] 不是 [] double

2）字典没有添加属性。它确实有添加方法：



尝试：

Two problems:
1) In C# an array of doubles is declared as double[] not []double
2) A Dictionary does not have an "add" property. It does have an Add method though:

Try:

Dictionary<double[] , string> x = new Dictionary<double[] , string>();
Dictionary<double[] , string> y = new Dictionary<double[] , string>();
x.Add(File.ReadAllLines(@"E:\TestFile.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"x array");
y.Add(File.ReadAllLines(@"E:\TestFile2.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"y array");

但是我不知道它是否会起作用......但它应该编译！

But I have no idea if it will work...but it should compile!

如果SomeDATAFile.txt包含新行分隔的有效条目可以解析为您的桌面上存在类型double，这将工作：

If "SomeDATAFile.txt" containing newline separated valid entries that can be parsed into Type double exists on your Desktop, this will work:

private string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Dictionary<double[] , string> x = new Dictionary<double[] , string>();

double[] xAry = File.ReadAllText(path + @"\SomeDATAFile.txt")
    .Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
    .Select(s => double.Parse(s)).ToArray();

x.Add(xAry,"x array");

我想建议您可以更好地回答这样的问题（在StackOverFlow以及此处询问）如果您：



1 。给出你正在使用的源代码的链接：对于DTW类：[ ^ ]



2.在CodeProject上，使用编辑器格式化代码，就像在StackOverFlow上一样。



3.清楚地描述所有错误信息。



4.回答直接问你的问题：不要重新发布代码。



您可能知道，Visual Studio Express是免费的;如果您可以离线编译，我认为您的工作效率会提高。

I'd like to suggest that you can get better responses to questions like this (asked on StackOverFlow as well as here) if you:

1. give links to the source code you are using: for the DTW Class: [^]

2. On CodeProject, use the editor to format your code like you did on StackOverFlow.

3. clearly describe all error messages.

4. respond to questions asked you directly: do not repost code.

As you may know, Visual Studio Express is free; I think your productivity will improve if you can compile off-line.
