基于文本文件定义项目(C#)

Question

我正在设置一个项目列表，如下所示。

List<BankInfo> all_branches = new List<BankInfo>();
Equipment.set_slot = "Mail";
all_branches.Add(new BankInfo
{
    name = "West Bank",
    city = "San Francisco",
    owner = new Person { name = "Jeff Bridges", age = 55 }
});
all_branches.Add(new BankInfo
{
    name = "East Bank",
    city = "Concord",
    owner = new Person { name = "Upton Sinclair", age = 102 }
});

从字面上看，编写成百上千个这样的代码是相当麻烦的，我更喜欢这样写

--
Name: West Bank
City: San Francisco
Owner: Jeff Bridges, 55
--
Name: East Bank
City: Concord
Owner: Upton Sinclair, 102

有没有办法做到这一点呢？

至少，有没有办法(在c#中)让像$ITEM这样的符号变成all_branches.Add(新的BankInfo {这样我就可以只做$ITEM (就像C++中的宏)？)

Answer 1

我理解您所指的是一个负责所有属性分配的函数：

private List<BankInfo> addToBankInfo(string name, string city, string owner_name, int owner_age, List<BankInfo> all_branches)
{
     return all_branches.Add(new BankInfo { name = name, city = city, owner = new Person { name = owner_name, age = owner_age } });
}

你可以调用它：

List<BankInfo> all_branches = new List<BankInfo>();
Equipment.set_slot = "Mail";
try
{
    using (System.IO.StreamReader sr = new System.IO.StreamReader("input_file.txt"))
    {
        string line;
        while ((line = sr.ReadLine()) != null)
        {
            if(line != null && line.Trim().Length > 0 && line.Contains(","))
            {
                string[] temp = line.Split(',');
                if(temp.Length >= 4)
                {
                    all_branches = addToBankInfo(temp[0], temp[1], temp[2], Convert.ToInt32(temp[3]), all_branches);
                }
            }
        }
    }
}
catch
{
}

在上面的例子中，我假设所有的输入都在一个用逗号分隔的TXT文件中。如果您提供有关确切输入格式的更多信息，我可以相应地更新代码。
