与Properties.Settings不一致的可访问性？

Question

我试图编写一个快速的程序，当我将Properties.Settings赋给变量s时，错误就会出现。我试图将它赋值给这个变量，因为我的许多文本框都需要指定一个设置值，而且还有很多设置需要保存。

            }
        }
    }
}

错误是：

Error   1   Inconsistent accessibility: field type 'SharpDock.Properties.Settings' is less accessible than field 'SharpDock.SettingsWindow.s'   C:\Users\Lewis\Documents\Visual Studio 2013\Projects\SharpDock\SharpDock\SettingsWindow.cs  14  36  SharpDock

请帮帮我！我被这个错误困住了。

Answer 1

您需要使用Properties.Settings.Default，并且不需要实例化它的变量。如果希望使用别名使代码更小，请删除以下代码：

public Properties.Settings s = new Properties.Settings();

并在类声明之前添加以下内容：

using s = Properties.Settings.Default;

正如deathismyfriend评论的那样，您可以通过为重复代码创建方法来减少代码。

Answer 2

您的Settings保存在Properties.Settings.Default中，因此您应该使用它而不是声明您自己的设置。此外，还可以为同一事件订阅多个控件。您应该做的是，将所有abuttons订阅到aButton_Click事件，将ibuttons订阅到iButton_Click事件。这是您的代码已修复：

using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SharpDock

    public partial class SettingsWindow : Form

            LoadSettings();
        }

        private void LoadSettings()
        {
            app1.Text = Properties.Settings.Default.app1;
            app2.Text = Properties.Settings.Default.app2;
            app3.Text = Properties.Settings.Default.app3;
            app4.Text = Properties.Settings.Default.app4;
            app5.Text = Properties.Settings.Default.app5;
            app6.Text = Properties.Settings.Default.app6;
            ico1.Text = Properties.Settings.Default.ico1;
            ico2.Text = Properties.Settings.Default.ico2;
            ico3.Text = Properties.Settings.Default.ico3;
            ico4.Text = Properties.Settings.Default.ico4;
            ico5.Text = Properties.Settings.Default.ico5;
            ico6.Text = Properties.Settings.Default.ico6;
        }

        private void Accept_Click(object sender, EventArgs e)
        {
            Properties.Settings.Default.Save();
            MessageBox.Show("SharpDock", "You must restart the program for the changes to take effect.", MessageBoxButtons.OK, MessageBoxIcon.Information);

                if (ofd.ShowDialog() == DialogResult.OK)
                {
                    if (sender == ibutton1)
                    {
                        ico1.Text = ofd.FileName;
                        Properties.Settings.Default.ico1 = ofd.FileName;
                    }
                    else if (sender == ibutton2)
                    {
                        ico2.Text = ofd.FileName;

    }
}

您还需要从设置中引用的项在设置中设置：
