Question

我有 List< ValuePair> 对象: listuserRoleValuePair 。我必须添加 ixUser 和 name , 以作为我每个圆环列表中的数值对。我如何才能添加这个?

List<ValuePair> listUserRoleValuePair = new List<ValuePair>();
var ixUserList= _mapper1.FindUserRoleLike(sName);
User result = null;

foreach (var ixUser in ixUserList)
{
    result = new UserMapper(connection).FindById(ixUser);
    var name = result.SFirstName + " " + result.SLastName;

    //listUserRoleValuePair.Add(ixUser);
    // listUserRoleValuePair.Add(    
}

我的价值观对等类如下:

public class ValuePair
{
    private string _index;
    private string _sName;

    public ValuePair(string index, string sName)
    {
        _index = index;
        _sName = sName;
    }

    public string Index
    {
        get { return _index; }
        set { _index = value; }
    }

    public string SName
    {
        get { return _sName; }
        set { _sName = value; }
    }
}

Answer 1

提供 ixUser 是索引字符串, 请使用此代码 :

List<ValuePair> listUserRoleValuePair = new List<ValuePair>();
var ixUserList= _mapper1.FindUserRoleLike(sName);
User result = null;

foreach (var ixUser in ixUserList)
{
    result = new UserMapper(connection).FindById(ixUser);
    var name = result.SFirstName + " " + result.SLastName;
    listUserRoleValuePair.Add(new ValuePair(ixUser, name));
}

Answer 2

您可以使用 KeyValuePair 类 :

List<KeyValuePair<string,string>> listUserRoleValuePair = new List<KeyValuePair<string,string>>();

然后:

listUserRoleValuePair.Add(new KeyValuePair<string,string>(name, ixUser);

也可以使用词典代替列表。

Answer 3

listUserRoleValuePair.Add(new ValuePair(index, name));

Im, 不清楚您对象的索引值是什么, 但不管它是什么, 只要在上行替换它

Answer 4

在您的情况下,只能添加支持子对象类型的项目,您可以使用其中之一。

collection.Add(new ValuePair(index, Name))

or
collection.Add(new ValuePair(){Index = index,SName= Name});

或非常简单的创建对象和通过

Valuepair valpair = new ValuePair();
valpair.Index = index;
valpair.SName = name;

collection.Add(valpair);

Answer 5

试试这个

var pair = new ValuePair();
// somehow intialize pair
listUserRoleValuePair.Add(pair);

Answer 6

listUserRoleValuePair.Add(new ValuePair(ixUser, name));
