C# uses string like that 'dd MMMM yyyy HH:mm' to define format the date and time should be displayed in.
C＃使用类似'dd MMMM yyyy HH：mm'的字符串来定义应显示日期和时间的格式。
Equivalent of that in momentjs is 'DD MMMM YYYY HH:mm'.
在momentjs中相当于'DD MMMM YYYY HH：mm'。
Is there some function that can covert one format definition into the other regardless of what (legal) combination of format specifiers source format contains?
是否有某些功能可以将一种格式定义转换为另一种格式定义，而不管格式说明符源格式包含哪些（合法）组合？
Basically what I want is:
基本上我想要的是：
function toMomentJsFormatDefinition(cSharpFormatDefinition) {
// should convert all format strings described here https://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx
}
console.log(toMomentJsFormatDefinition('dd MMMM yyyy HH:mm'));
// outputs DD MMMM YYYY HH:mm
Ideally toMomentJsFormatDefinition should be defined in some already written and fairly well tested library I'll just use in my project.
理想情况下，toMomentJsFormatDefinition应该在一些已经编写且经过良好测试的库中定义，我将在我的项目中使用它。

I had the same task and created the following utility function to convert a DateTime Format String from Dotnet to MomentJS format.
我有相同的任务，并创建了以下实用程序函数来将DateTime格式字符串从Dotnet转换为MomentJS格式。
Usage:
用法：
string lDotNetFormat = "yyyy-MM-dd HH:mm";
string lMomentJSFormat = MomentJSHelpers.GenerateMomentJSFormatString(lDotNetFormat, fTolerant: true, fCulture: CultureInfo.InvariantCulture);
MessageBox.Show(lMomentJSFormat);
// Output: YYYY[-]MM[-]DD[ ]HH[:]mm
