boolis an alias for System.Booleanjust as intis an alias for System.Int32. See a full list of aliases here: Built-In Types Table (C# Reference).
bool是 的别名，System.Boolean就像int的别名一样System.Int32。在此处查看别名的完整列表：内置类型表（C# 参考）。

They are one in the same. bool is just an alias for Boolean.
他们是一样的。bool 只是 Boolean 的别名。

One is an alias for the other.
一个是另一个的别名。

They are the same. Boolean helps simplify conversion back and forth between C# and VB.Net. Most C# programmers tend to prefer 'bool', but if you are in a shop where there's a lot of both VB.Net and C# then you may prefer Boolean because it works in both places.
他们是一样的。Boolean 有助于简化 C# 和 VB.Net 之间的来回转换。大多数 C# 程序员往往更喜欢“bool”，但如果您所在的商店有很多 VB.Net 和 C#，那么您可能更喜欢 Boolean，因为它在这两个地方都适用。

As has been said, they are the same. There are two because bool is a C# keyword and Boolean a .Net class.
如前所述，它们是相同的。有两个，因为 bool 是 C# 关键字，而 Boolean 是 .Net 类。

bool is an alias for the Boolean class. I use the alias when declaring a variable and the class name when calling a method on the class.
bool 是 Boolean 类的别名。我在声明变量时使用别名，在类上调用方法时使用类名。
回答by Zach Burlingame
There is no difference - bool is simply an alias of System.Boolean.
没有区别 - bool 只是 System.Boolean 的别名。

I realise this is many years later but I stumbled across this page from google with the same question.
我意识到这是很多年后的事了，但我从 google 偶然发现了这个页面，上面有同样的问题。
There is one minor difference on the MSDN page as of now.
到目前为止，MSDN 页面上有一个细微差别。

Note:
If you require a Boolean variable that can also have a value of null, use bool. For more information, see Nullable Types (C# Programming Guide).
笔记：
如果您需要一个也可以具有 null 值的布尔变量，请使用 bool。有关更多信息，请参阅可空类型（C# 编程指南）。

Perhaps bool is a tad "lighter" than Boolean; Interestingly, changing this:
也许 bool 比 Boolean 更“轻”一点；有趣的是，改变这一点：
namespace DuckbillServerWebAPI.Models
{
public class Expense
{
. . .
public bool CanUseOnItems { get; set; }
}
}
...to this:
...到这个：
namespace DuckbillServerWebAPI.Models
{
public class Expense
{
. . .
public Boolean CanUseOnItems { get; set; }
}
}
...caused my cs file to sprout a "using System;" Changing the type back to "bool" caused the using clause's hair to turn grey.
...导致我的 cs 文件萌生了一个“使用系统”；将类型改回“bool”会导致 using 子句的头发变灰。
