c# - 使用默认参数重载构造函数

Question

我不小心在 C# 中重载了一个构造函数，如下所示:

public MyClass(string myString) 
{
    // Some code goes here 
}

public MyClass(string myString, bool myParameter = false) 
{
   // Some different code here
}

使用这段代码，我的项目编译得很好。如果我仅使用 string 参数调用构造函数，C# 如何决定我要使用哪个构造函数？为什么在语法上允许此功能？

If two candidates are judged to be equally good, preference goes to a candidate that does not have optional parameters for which arguments were omitted in the call. This is a consequence of a general preference in overload resolution for candidates that have fewer parameters.
