表格關閉之後：button.performclick

Question

請幫我解決這個表單關閉後點擊按鈕執行，因爲我只依靠windows關閉按鈕（右上角），我沒有使用額外的按鈕來關閉表格。 但是，這個程序仍然在工作，但不會在保存.ini文件後立即自動關閉表單。

我希望表單在button1.performclick（）後關閉...但我不知道該怎麼辦..

我有以下代碼：

int beFore, afTer; 
    private void Form3_Load(object sender, EventArgs e) 
    { 
     beFore = this.checkedListBox1.CheckedIndices.Count + 
       this.checkedListBox2.CheckedIndices.Count + 
       this.checkedListBox3.CheckedIndices.Count + 
       this.checkedListBox4.CheckedIndices.Count; 
    } 
    //private Form4 subForm4 = new Form4(); 
    private void Form3_FormClosing(object sender, FormClosingEventArgs e) 
    { 
     afTer = this.checkedListBox1.CheckedIndices.Count + 
       this.checkedListBox2.CheckedIndices.Count + 
       this.checkedListBox3.CheckedIndices.Count + 
       this.checkedListBox4.CheckedIndices.Count; 
     while (beFore != afTer) 
     { 
      if (MessageBox.Show("Changes have been made..\r\nSave to configuration file (.ini) ?", "Warning", 
       MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes) 
      { 
       this.button1.PerformClick(); //need to close this form after button.performclick.. 
       this.UpdateForm1(); 
       break; 
      } 
      else 
      { 
       this.UpdateForm1(); 
       break; 
      } 
     } 
     beFore = afTer; 

    } 

    private void UpdateForm1() 
    { 
     Form4 subForm4 = new Form4(); 
     subForm4.Show(); 
     subForm4.Update(); 
     try 
     { 
      int checkagain1 = this.checkedListBox1.CheckedIndices.Count; this.checkedListBox1.SetItemChecked(2, true); 
      int checkagain2 = this.checkedListBox2.CheckedIndices.Count; this.checkedListBox2.SetItemChecked(2, true); 
      int checkagain3 = this.checkedListBox3.CheckedIndices.Count; this.checkedListBox3.SetItemChecked(2, true); 
      int checkagain4 = this.checkedListBox4.CheckedIndices.Count; this.checkedListBox4.SetItemChecked(2, true); 

      Form1 myParentForm = (Form1)this.Owner; 
      if (myParentForm.comboBox1.Text.Length != 0) 
      { 
       //myParentForm.Enabled = false; 
       myParentForm.method1(); 
       myParentForm.method2(); 
       myParentForm.method3(); 
       myParentForm.method4(); 
       //myParentForm.Enabled = true; 
       subForm4.Close(); 
      } 

     } 
     catch (Exception) 
     { 
      subForm4.Close(); 
      return; 
      throw; 
     } 
    } 

Answer 1

我不是100％肯定，你想要什麼，但我敢肯定，你正在尋找的答案是形式的DialogResult屬性。

如果您的問題是一個按鈕正在關閉窗體，當您單擊它，然後爲窗體的DialogResult屬性設置DialogResult.None。

DialogResult = DialogResult.None; 

Answer 2

我沒有正確理解你，但如果你想關閉窗體如果結果是肯定的，你可以這樣做。

if (MessageBox.Show("Changes have been made..\r\nSave to configuration file (.ini) ?", "Warning", 
       MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes) 
      { 
       this.Dispose(); 
       this.Close(); 
      } 

，如果你想這這種地方處置清潔程序使用，然後將其關閉，或者關閉關閉窗體直接

或嘗試做這一切的資源：

private void button1_Click(object sender, EventArgs e) 
     { 
      this.Dispose(); 
      this.Close(); 
     } 

    if (MessageBox.Show("Changes have been made..\r\nSave to configuration file (.ini) ?", "Warning", 
        MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes) 
       { 
        button1.PerformClick(); 
       }
