我需要搜索爲特定的用戶生成的輸入創建的對象數組，並返回包含輸入的相同元素的內容之一

Question

我創建了一個名爲DictionarySample的類來表示此類中的過程是應該複製幾個類似的Dicitionary功能

public class DictionarySample 
    { 
     public int idNumb {get; set;} 
     public string fn { get; set; } 
     public string ln { get; set; } 
     public string adr { get; set; } 
     public string bday { get; set; } 
     public int num { get; set; } 

    } 

通過我已經在表單類中啓動的數組。

namespace Project 
{ 
    public partial class Form1 : Form 
    { 
     public int lastElementIndex = 0; 
     DictionarySample[] database = new DictionarySample[1000]; 
     PriorityQueueSample[] line = new PriorityQueueSample[1000]; 

    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 


    } 

    public void buttonApply_Click(object sender, EventArgs e) 
    { 
     bool digitCharactersInfirst = textBoxFirstName.Text.Any(char.IsDigit); 
     bool digitCharactersInlast = textBoxLastName.Text.Any(char.IsDigit); 

     if (String.IsNullOrEmpty(textBoxIDNumber.Text)) 
     { 
      MessageBox.Show("Enter an ID Number.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else if (int.Parse(textBoxIDNumber.Text) < 100000 || int.Parse(textBoxIDNumber.Text) > 999999) 
     { 
      MessageBox.Show("Invalid ID Number.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 

     } 
     else if (String.IsNullOrEmpty(textBoxFirstName.Text)) 
     { 
      MessageBox.Show("Enter First Name.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else if (digitCharactersInfirst == true) 
     { 
      MessageBox.Show("First Name can't contain digits. Please re-enter Given Name.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
      textBoxFirstName.Text = String.Empty; 
     } 
     else if (String.IsNullOrEmpty(textBoxLastName.Text)) 
     { 
      MessageBox.Show("Enter Last Name.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else if (digitCharactersInlast == true) 
     { 
      MessageBox.Show("Last Name can't contain digits. Please re-enter Surname.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
      textBoxLastName.Text = String.Empty; 
     } 
     else if (String.IsNullOrEmpty(textBoxAdr.Text)) 
     { 
      MessageBox.Show("Enter Address.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else if (String.IsNullOrEmpty(textBoxBirthday.Text)) 
     { 
      MessageBox.Show("Enter Date of Birth.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else 
     { 

      string c = "Proceed with the following Account Information? \n" + textBoxFirstName.Text + " " + textBoxLastName.Text + "," + textBoxIDNumber.Text + "\nAddress: " + textBoxAdr.Text + "\nBirthday: " + textBoxBirthday.Text; 


      DialogResult dialogResult = MessageBox.Show(c, "Verify information", MessageBoxButtons.YesNo); 
      if (dialogResult == DialogResult.Yes) 
      { 
       int a = int.Parse(textBoxIDNumber.Text); 
       lastElementIndex++; 
       DictionarySample d = new DictionarySample(); 
       d.idNumb = a; 
       d.fn = textBoxFirstName.Text; 
       d.ln = textBoxLastName.Text; 
       d.adr = textBoxAdr.Text; 
       d.bday = textBoxBirthday.Text; 
       d.num = lastElementIndex; 
       database[lastElementIndex] = d; 
       textBoxIDNumber.Text = String.Empty; 
       textBoxFirstName.Text = String.Empty; 
       textBoxLastName.Text = String.Empty; 
       textBoxAdr.Text = String.Empty; 
       textBoxBirthday.Text = String.Empty; 


       string prio = "You may now Line-Up.\nYour priority number is:\t" + lastElementIndex; 
       MessageBox.Show(prio, "Take Note", MessageBoxButtons.OK); 
      } 
      else if (dialogResult == DialogResult.No) 
      {      
      } 
     } 

程序是這樣的：它要求用戶爲IDNumber中，姓名，地址和生日，然後在內部根據其應用的順序，對生成優先數，其在的「應用」點擊按鈕將用戶信息存儲在我的數組名爲database中。

退房形式的屏幕截圖的用戶已申請後，他便不得不投入第二面板，在陣容點擊按鈕必須尋找自己的ID號碼數據庫中的ID號並返回相應的優先級號，然後將它們插入具有優先級隊列功能的另一個陣列中。

我這個陣容點擊按鈕當前的代碼去如下

private void buttonLineUp_Click(object sender, EventArgs e) 
    { 

     int temp = int.Parse(textBoxIDLINE.Text); 
     if (String.IsNullOrEmpty(textBoxIDLINE.Text)) 
     { 
      MessageBox.Show("Enter an ID Number.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else if (int.Parse(textBoxIDLINE.Text) < 100000 || int.Parse(textBoxIDLINE.Text) > 999999) 
     { 
      MessageBox.Show("Invalid ID Number.", "Invalid Input", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); 
     } 
     else 
     { 
      for (int looper = 0; looper < 500; looper++) 
      { 
       //if (d.idNumb.database[looper] == int.Parse(textBoxIDNumber.Text)) 
       //{ 
       //} 
       //int idnb = 0; 
       //int priorityk = 0; 

       foreach (DictionarySample d in database) 
       { 
        if (d.idNumb == int.Parse(textBoxIDNumber.Text)) 
        { 
         PriorityQueueSample lin = new PriorityQueueSample(); 
         lin.idNumber = d.idNumb; 
         lin.pnumb = d.num; 

         labeldisplay.Text = d.idNumb + "," + d.num; 
        } 


       } 

      } 

     } 

我還沒有開始將數據輸入到時Queue陣列，因爲我無法從數據庫陣列訪問數據。請幫忙。

Answer 1

如果idNumb是獨一無二的，而不是隨後的：

DictionarySample[] database = new DictionarySample[1000]; 

你可以使用：

Dictionary<int, DictionarySample> = new Dictionary<int, DictionarySample>(); 

然後是idNumb保存作爲字典的關鍵。
