Question

我有一个名为SoftwareRosterForm的表单：

namespace WpfsoftwareMonitoring.views
{

    public partial class SoftwareRosterForm : Window
    {
        public SoftwareRosterForm()
        {
            InitializeComponent();
        }
    }
}

和SoftwareRosterClass：

namespace WpfsoftwareMonitoring
{
    class SoftwareRosterClass
    {
        ConnectionManager DatabaseConnect = new ConnectionManager();
        DataSet SoftwareData = new DataSet();

        public void AddSoftwareFunction(SoftwareRosterForm SoftwareRosterPage)
        {
            if (SoftwareRosterPage.SoftName_txtbox.Text == "" || SoftwareRosterPage.SoftType_cmbbox.Text == "")
            {
                MessageBox.Show("Complete all the fields.");
            }
            else
            {
                DatabaseConnect.StringQuery = "SELECT * FROM SoftwareList_tbl WHERE Software_name = '" + SoftwareRosterPage.SoftName_txtbox.Text + "'";
                DatabaseConnect.GetData();
                if (DatabaseConnect.SQLDR.HasRows == true)
                {
                    DatabaseConnect.SQLDR.Close();
                    SoftwareRosterPage.SoftName_txtbox.SelectAll();
                    MessageBox.Show("Software already exist.");
                }

                else
                {
                    DatabaseConnect.SQLDR.Close();
                    DatabaseConnect.StringQuery = "INSERT INTO SoftwareList_tbl (Software_name, Software_type) VALUES ('" + SoftwareRosterPage.SoftName_txtbox.Text + "', '" + SoftwareRosterPage.SoftType_cmbbox.Text + "')";
                    DatabaseConnect.InsertData();
                    MessageBox.Show("Software added.");
                    DatabaseConnect.SQLDR.Close();
                    ClearFormFields(SoftwareRosterPage);
                    FilterSoftwareList(SoftwareRosterPage);
                    SoftwareRosterPage.SoftName_txtbox.Focus();
                }
            }
        }
        public void FilterSoftwareList(SoftwareRosterForm SoftwareRosterPage)
        {
            //SoftList_lstview.Items.Clear();
            DatabaseConnect.StringQuery = "SELECT Software_name, Software_type FROM SoftwareList_tbl";
            DatabaseConnect.GetData();
            DatabaseConnect.SQLDR.Close();

            //Fills the temporary table with the selected data and fills the list view
            DatabaseConnect.SQLDA.Fill(SoftwareData);
            SoftwareRosterPage.SoftList_lstview.DataContext = SoftwareData.Tables[0].DefaultView;

            DatabaseConnect.SQLDR.Close();
        }

        public void ClearFormFields(SoftwareRosterForm SoftwareRosterPage)
        {
            SoftwareRosterPage.SoftName_txtbox.Clear();
            SoftwareRosterPage.SoftType_cmbbox.SelectedIndex = -1;
        }
    }
}

我尝试在public void AddSoftwareFunction(SoftwareRosterForm SoftwareRosterPage)方法中传递SoftwareRosterForm但发生错误：

找不到类型或命名空间名称'SoftwareRosterForm'（您是否缺少using指令或程序集引用？）

但是当我删除命名空间WpfsoftwareMonitoring.Views中的“视图”时，错误不会发生，而是出现了另一个错误：

当前上下文中不存在名称“InitializeComponent”

任何想法？我将表单放在Views文件夹中，我尝试删除它运行良好的文件夹中的表单，但我需要将表单放在文件夹中以保持整洁

Answer 1

您需要将WpfsoftwareMonitoring.views命名空间添加到您的类文件

示例：

using WpfsoftwareMonitoring.views

namespace WpfsoftwareMonitoring
{
    class SoftwareRosterClass
    {
      ..............

将wpf窗口放在一个文件夹中
