Question

我正在使用c＃

我的变量中有以下字符串。

string results = "Mr,Mike,Lewis,32,Project Manager,India";

现在我想在会话变量的Dictionary类型中添加这些值。我在代码中声明了一个dict类型变量。

Dictionary<string, string> skywardsDetails = new Dictionary<string, string>();

立即写下我编写的代码如下：

if (!string.IsNullOrEmpty(results))                                            
{                                                
    string[] array = results.Split(',');
    string title = array[0];
    string firstname = array[1];
    string lastname = array[2];
    string age = array[3];
    string designation = array[4];    
    string country = array[4];    

    //Here I want to write the new code which will add the results.Split(',') values in my Session variable as a Dictionary type.                                       

    foreach (string key in results.Split(','))
    {
    skywardsDetails.Add(key,//What to do here)
    }
}

请建议

Answer 1

您的CSV results变量不代表字典。它代表Employee模型：

public class Employee
{
    public string Title { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }
    public string Designation { get; set; }
    public string Country { get; set; }
}

然后：

var tokens = (results ?? string.Empty).Split(',');
if (tokens.Length > 5)
{
    var employee = new Employee
    {
        Title = tokens[0],
        FirstName = tokens[1],
        LastName = tokens[2],
        Age = int.Parse(tokens[3]),
        Designation = tokens[4],
        Country = tokens[5]
    };
    // TODO: do something with this employee like adding it
    // to some dictionary, session, whatever
}

Answer 2

你不能在这里真正使用foreach而不是声明局部变量用

替换该部分

    skywardsDetails["title"] = array[0];
    skywardsDetails["firstname"] = array[1];
    skywardsDetails["lastname"] = array[2];
    skywardsDetails["age"] = array[3];
    skywardsDetails["designation"] = array[4];    
    skywardsDetails["country"] = array[5];

现在将这些字符串常量移动到某个常量，如const string Title =“title”，您将能够从字典中获取所需的字段数据，如

string title= skywardsDetails[Constants.Title]

Answer 3

使用这样的词典会更有意义：

skywardsDetails.Add("Title", array[0]);
skywardsDetails.Add("FirstName", array[1]);
// etc.

您不应该使用实际值作为键，因为我认为您需要一种通用的方式来访问它们。

Answer 4

尝试这样的事情：

enum UserData
{
    Title,
    Firstname,
    Lastname,
    Age,
    Designation,
    Country  
}
//========================================================
string results = "Mr,Mike,Lewis,32,Project Manager,India";
string[] array = results.Split(',');
var skywardsDetails = new Dictionary<UserData, string>();
// maybe you need some check data here
for (int i = 0; i < array.Length; i++)
{
    skywardsDetails[(UserData)i] = array[i];
}
