Question

我正在为阅读文章制作一个网络应用程序。

我有bool属性，如果单击特定Edit按钮，则设置为true，在Save和其他控件上填写用户信息后，还有一个TextBoxes按钮被单击。每当我运行我的应用程序并填充信息时，它运行正常，但在运行4或5次运行（重新启动应用程序）后，单击Save按钮时会出现异常错误： Input string was not in a correct format由于填充TextBoxes为Null（首先，Null被转换为Int）。

我的问题是bool属性（Managment.IsEditing）没有任何原因设置为true（应按Edit按钮将bool设置为true）。为什么以及如何自动设置为true，因为其代码仅在EditButton_Click事件中被调用？

以下是代码

protected void EditButton_Click(object sender, EventArgs e)
{
    if(EditorList.SelectedIndex > -1) //Just to ensure that Item is selected from ListBox
    {   
        //editor is the poco  , EditorManager is the editor table manager
        editor = EditorManager.GetEditorInfo(EditorList.SelectedValue);

        NameTextBox.Text = editor.Name;
        EmailTextBox1.Text = editor.Email;
        PasswordTextBox.Text = editor.Password;
        EditorIDTextBox.Text = editor.Editor_ID.ToString();

        for (int index = 0; index < RoleCheckBoxList.Items.Count; index++)
        {
          RoleCheckBoxList.Items[index].Selected = editor.RoleList[index];
        }

        Managment.IsEditing = true; //This flag is responsible for telling "SaveButtton" that editor would be updated. 
        DeleteButton.Enabled = true;
        ResultLabel.Text = "";
    }

    else
        ResultLabel.Text = "Select Editor from list first";

protected void SaveButton_Click(object sender, EventArgs e)
{
    if(Managment.IsEditing == false) //it makes sure that new editor is being saved
    {
        editor.Name = NameTextBox.Text;
        string email = EmailTextBox1.Text;
        editor.Email = email.ToLower();
        editor.Password = PasswordTextBox.Text;

        if(EditorManager.IsEditorValid(editor.Email))
        {
            for (int index = 0; index < RoleCheckBoxList.Items.Count; index++)
            {
              editor.RoleList[index] = RoleCheckBoxList.Items[index].Selected;
            }

            EditorManager.Save(editor);
            ResultLabel.Text = editor.DataUploadMessage;            
        }

        else
            ResultLabel.Text = "Editor with the same Email can't be add!";

        FillEditorList();
    }

    else if(Managment.IsEditing == true) //it determines that existing editor is being updated and problem is that Managment.IsEditing is turned on without being called.
    {
        editor.Name = NameTextBox.Text;
        string email = EmailTextBox1.Text;
        editor.Email = email.ToLower();
        editor.Password = PasswordTextBox.Text;
        editor.Editor_ID = Convert.ToInt32(EditorIDTextBox.Text);// Error occurs at this line

        for (int index = 0; index < RoleCheckBoxList.Items.Count; index++)
        {
          editor.RoleList[index] = RoleCheckBoxList.Items[index].Selected;
        }

        EditorManager.Edit(editor);

        ResultLabel.Text = editor.DataUploadMessage;
        Managment.IsEditing = false;
        FillEditorList();            
    }
    ClearFields(Form.Controls);
}

该行发生异常：

editor.Editor_ID = Convert.ToInt32(EditorIDTextBox.Text);

对于给亲们带来的任何不便表示歉意

当指示的行发生异常时，将不会运行重置您的标志的行。然后该页面可能处于无效状态。

尝试修复/处理错误并正确清理，问题可能会消失。

Bool属性设置为true而不调用
