Please ai have a Questions , I need find the higghest value in array. 请给我一个问题,我需要在数组中找到最大的值。 To the array will people write name (textbox1) and money (texbox2). 人们会在数组中输入名称(textbox1)和货币(texbox2)。 I have 2 buttons first button is save to the array and second write the name with the biggest money. 我有2个按钮,第一个按钮保存到数组中,第二个用最大的钱写下名字。

Code for save: 保存代码:

    string[] name = new string[50];
    int items = 0;
    int[] money = new int[50];

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            Convert.ToInt32(textBox2.Text);
        }
        catch
        {
            name[items] = textBox1.Text;
            money[items] = Int32.Parse(textBox2.Text);
            items++;        
        }
    }

And to the button2 need search the biggest value and write name! 并向button2需要搜索最大的值并写下名称! Please help me 请帮我

 private void button2_Click(object sender, EventArgs e)
 {
    int maxIndex = 0;

    for(int i = 0; i < 50; i++)
    {
        if (money[i] > money[maxIndex])            
            maxIndex = i;            
    }

    MessageBox.Show(name[maxIndex] + " has biggest value " + money[maxIndex]);
 }    

To get the Max int from your array you can use IEnumerable.Max : 要从数组中获取Max int,可以使用IEnumerable.Max

money.Max();

But there could be more than one name with the same high money value, perhaps you need to handle this also, I think Dictionary would be your best option 但是可能会有不止一个名字具有相同的高额货币价值,也许您也需要处理这个问题,我认为Dictionary将是您的最佳选择

private Dictionary<string, int> Names = new Dictionary<string, int>();

private void button1_Click(object sender, EventArgs e)
{
    int value = 0;
    if (int.TryParse(textBox2.Text, out value))
    {
        if (!Names.ContainsKey(textBox1.Text))
        {
            Names.Add(textBox1.Text, value);
        }
    }
}

private void button2_Click(object sender, EventArgs e)
{
    if (Names.Any())
    {
        int maxMoney = Names.Max(v => v.Value);
        var names = Names.Where(k => k.Value.Equals(maxMoney));
        foreach (var name in names)
        {
            // Names with the highest money value
        }
    }
}
