组装参考缺少指令 [英] Missing directive of assembly reference

问题描述

我添加了现有的形式（和它的引用）到另一个项目，我试图以显示新的形式。有没有编码的问题，只是一个参考错误：

I added an existing form (and it's references) to another project and I am trying to show the new form. There are no coding issues, just a reference error:

类型或命名空间frmEmail'找不到（是否缺少
按指令或程序集引用？）

The type or namespace 'frmEmail' could not be found (are you missing a using directive or an assembly reference?)

我无法弄清楚什么是使用或参考导入时我没有使用的其他形式。 ？任何想法

I cannot figure out what "using" or reference I failed to use when importing the other form. Any ideas?

下面是调用错误的代码：

Here is the code calling the error:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Notify_Setup
{
public partial class frmNotifications : Form
{
    public frmNotifications()
    {
        InitializeComponent();
        pbBlue.MouseEnter += new EventHandler(pbBlue_MouseEnter);
    }
    private void pbGreen_Click(object sender, EventArgs e)
    {
        frmEmail frmEmail = new frmEmail();
        frmEmail.Show();
        this.Hide();
    }
}

}

}

推荐答案

您需要拉命名空间。例如，如果这是你的表目前是如何在其他项目：

You need to pull the namespace in. For example, if this was how your form currently was in the other project:

namespace Your.Form.Namespace { // this is important
    public class YourForm : Form {
        // stuff
    }
}

然后在项目中您要添加到..你需要添加组件，引用，然后导入命名空间中是这样的：

Then in the project you're adding it to.. you need to add your assembly as a reference, then import the namespace in like this:

using Your.Form.Namespace; // import the namespace

namespace Other.Project {
    public class OtherClass {
        YourForm _form; // this is fine now
    }
}

其他的选项就是完全限定的类型。这意味着什么，是在声明中使用整个空间和类型名称。这将是这样的：

The other options is to fully qualify the type. What this means, is to use the entire namespace and type name in the declaration. It would be like this:

namespace Other.Project {
    public class OtherClass {
        Your.Form.Namespace.YourForm _form; // this is fine too
    }
}
