请问关于c的具体应用场景有哪些？

本文共计313个文字，预计阅读时间需要2分钟。

通过使用Microsoft文档和完成教程，我正在研究类和对象模块。以下是一个简化的BankAccount类示例：

csharpusing System;namespace classes{ public class BankAccount { public string Number { get; } public string Owner { get; set; } public decimal Balance { get; }

public BankAccount(string number, string owner, decimal balance) { Number=number; Owner=owner; Balance=balance; } }}

通过Microsoft文档和完成教程,我目前正在研究类和对象模块.

using System; namespace classes { public class BankAccount { public string Number { get; } public string Owner { get; set; } public decimal Balance { get; } public BankAccount(string name, decimal initialBalance) { this.Owner = name; this.Balance = initialBalance; } public void MakeDeposit(decimal amount, DateTime date, string note) { } public void MakeWithdrawal(decimal amount, DateTime date, string note) { } }

}

是我们开始的,我将调用此类作为Program.cs文件中的测试

using System; namespace classes { public class Program { var account = new BankAccount("<HAMID>", 1000); Console.WriteLine($"Account {account.Number} was created for {account.Owner} with {account.Balance} initial balance."); } }

但我在Console.WriteLine(“…”)中收到此错误

"Type expected , tuple must be at least two elements, ) expected, invalid token $"Account {account.Number} was created for {account.Owner} with {account.Balance} initial balance."

欣赏有关我的困境的任何见解.

您缺少Program类中的静态void Main(string [] args)方法.

例：

using System; namespace classes { class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); } } }
