VB“ Financial.Pmt”等价于C＃？ [英] VB "Financial.Pmt" equivalent in C#?

问题描述

Microsoft.VisualBasic程序集有一个内置函数。我可以像这样在VB中使用它：

There is a built in function from the Microsoft.VisualBasic assembly. I can use it in VB like this:

Financial.Pmt((dAPR / 100) / 12, iNumberOfPayments, dLoanAmount) * -1

我当前的项目在C＃中，我需要使用此功能。网络上的答案说，只需添加名称空间和程序集，并在C＃中使用相同的名称，但这是不对的！ C＃仍然无法识别该公式。

My current project is in C# and I need to use this function. Answers on the web say just add the namespace and assembly and use the same in C#- but this is not true! C# still does not recognize this formula.

那么我该如何在C＃中使用use Financial.Pmt（甚至可以将源代码移植到该代码中）？谢谢您的帮助。

So how can I use use Financial.Pmt in C# (or perhaps even porting the source code to it)? Thanks for any help.

推荐答案

像这样：

using System;
using Microsoft.VisualBasic;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            double dAPR = 2;
            Int32 iNumberOfPayments = 12;
            double dLoanAmount = 10000;
            Console.WriteLine(Financial.Pmt((dAPR / 100) / 12, iNumberOfPayments, dLoanAmount, 0, DueDate.EndOfPeriod) * -1);
            Console.ReadLine();
        }
    }
}

• 类似于 Joel说，添加对Microsoft的引用。 VisualBasic程序集。


• 就像Rup在评论中说的那样，您必须为第4个和第5个参数提供默认值。


• Like Joel says, add a reference to the Microsoft.VisualBasic assembly.
• Like Rup says in a comment, you have to provide the defaults to the 4th and 5th arguments.

请在适当的时候使用C＃中的Microsoft.VisualBasic 。它是.Net中受完全支持的核心库，并且包含一些有用的财务功能。

Do use Microsoft.VisualBasic from C# when appropriate. It's a fully supported core library in .Net and it contains some useful financial functions.
