Print the contents of an array (code is one line, for use in Immediate window of visual studio)
提问by MedicineMan
Can you write a convenient line of code that prints the contents of an array?
你能写一行方便的代码来打印数组的内容吗？
I will use this in the Immediate Window of Visual Studio 2008, so really it has to work in that window. I may have left out some requirements, but that's pretty much what I'm trying to do.
我将在 Visual Studio 2008 的即时窗口中使用它，因此它必须在该窗口中工作。我可能遗漏了一些要求，但这几乎就是我想要做的。

myArray.ToList().ForEach(Console.WriteLine);
Honestly though, I don't think that'll work in the immediate window. It is a nice trick to print it all in one line, but I think for the immediate window, all you need is this:
老实说，我认为这不会在直接窗口中起作用。将其全部打印在一行中是一个不错的技巧，但我认为对于直接窗口，您只需要这样：
? myArray

Might be easier to just use the watch tab. But simply typing the name of the array in the immediate tab should return the contents in a somewhat useful format.
仅使用监视选项卡可能更容易。但是，只需在立即选项卡中键入数组的名称，就会以某种有用的格式返回内容。

For both the Watch and Immediate windows in Visual Studio, the string returned by ToString() for an object will be used.
对于 Visual Studio 中的 Watch 和 Immediate 窗口，将使用 ToString() 为对象返回的字符串。
So you can override ToString() if you want and format the human-readable representation of any of your classes so that they display the information you need in the Watch or Immediate windows during debugging activities.
因此，您可以根据需要覆盖 ToString() 并格式化任何类的人类可读表示，以便它们在调试活动期间在 Watch 或 Immediate 窗口中显示您需要的信息。
For example,
例如，
public class Foo
{
public String Bar { get; set; }
private Int32 _intValue;
public Int32 Value { get { return _intValue; } }
override public ToString()
{
return "Bar: " + Bar + " has Value: " + Value;
}
}
So now if you create an array of Foo objects named fooArray, typing ? fooArray in the Immediate window will list all the Foo objects with the ToString() return value for each in curly braces. Something like this:
所以现在如果你创建一个名为 fooArray 的 Foo 对象数组，输入 ? 立即窗口中的 fooArray 将列出所有带有 ToString() 返回值的 Foo 对象，每个对象都用花括号括起来。像这样的东西：
? fooArray
{Foo[2]}
[0]: {Bar: hi has Value: 1}
[1]: {Bar: there has Value: 2}

I had this problem with the byte array contained within a MemoryStream - I found this worked to view the contents of the MemoryStream in the Visual Studio 2010 Watch window:
我在 MemoryStream 中包含的字节数组遇到了这个问题 - 我发现这可以在 Visual Studio 2010 Watch 窗口中查看 MemoryStream 的内容：
System.Text.ASCIIEncoding.ASCII.GetString(((((System.IO.MemoryStream)(s)))._buffer))

String.Join("; ", myArray);
- String.Join Method (String, String[])(.NET 2.0 and newer)
- String.Join Method (String, Object[])(.NET 4.0 and newer)
- String.Join Method (String, IEnumerable)(.NET 4.0 and newer)
- String.Join 方法 (String, String[])（.NET 2.0 和更新版本）
- String.Join 方法 (String, Object[])（.NET 4.0 及更新版本）
- String.Join 方法（字符串，IEnumerable）（.NET 4.0 和更新版本）

I use:
我用：
BitConverter.ToString(bytes); //output: 4A-0B-11-13 etc.
Poor BitConverter, always forgotten.
可怜的BitConverter，总是被遗忘。

Remember that you can reference a method in the program you are debugging. I have a utility method (let's say it's in a MyDebug class):
请记住，您可以在正在调试的程序中引用方法。我有一个实用方法（假设它在 MyDebug 类中）：
public static string ToReadableString(byte[] data)
{
int length = data.Length;
var sb = new StringBuilder(length);
for (int index = 0; index < length; ++index)
{
char ch = (char)data[index];
sb.Append(Char.IsControl(ch) ? '.' : ch);
}
return sb.ToString();
}
and (since my array is named data) add a Watch statement:
并且（因为我的数组名为 data）添加一个 Watch 语句：
MyDebug.ToReadableString(data)

You can always create a second variable with the content that you want and check for the value of that.
您始终可以使用所需的内容创建第二个变量并检查其值。
var ids = people.Select(s => s.id).ToList();
Would return all of the ids that you are trying to see.
将返回您尝试查看的所有 ID。

If you want print for example a array mof type float[4][4]just type:(float(*)[4][4])m
如果你想打印例如一个m类型的数组，float[4][4]只需输入：(float(*)[4][4])m
