c# - 字符串替换c#为地址缩写

Question

我有一个转换代码，但某些地址的结果与预期不同。

23 Starling St => 3 Streetarling Street 错了，应该是23 Starling Street

1 St Johns Ct => 1 Street Johns Ct => Correct

这是代码:

private string StreetConversion(string address, Order order)
{
    string[] addressList = address.Split(' ');

    foreach (string add in addressList) 
    {
        if(add == "pde")
            address = address.Replace("pde", "Parade");
        if (add == "Pde")
            address = address.Replace("Pde", "Parade");
        if (add == "Rd")
            address = address.Replace("Rd", "Road");
        if (add == "rd")
            address = address.Replace("rd", "Road");
        if (add == "St")
            address = address.Replace("St", "Street");
        if (add == "st")
            address = address.Replace("st", "Street");
    }

    order.ShipAddress1 = address;
    return address;
}

您需要替换给定的单词而不是 replacing all occurences地址变量中的那个词，

private string StreetConversion(string address, Order order)
{
    string[] addressList = address.Split(' ');
    StringBuilder newAddress = new StringBuilder();

    foreach (string add in addressList) 
    {
        if(add.ToLower() == "pde")
            newAddress.Append("Parade ");
        else if (add.ToLower() == "rd")
            newAddress.Append("Road ");
        else if (add.ToLower() == "st")
            newAddress.Append("Street ");
        else
            newAddress.Append(add+ " ");
    }

    order.ShipAddress1 = newAddress.ToString();
    return newAddress.ToString();
}
