创建使用表单在C＃的输入框 [英] Creating an Inputbox in C# using forms

问题描述

您好，我目前正在创建具有需要服务器的IP地址添加到它，因为在C＃中没有InputBox函数我试图完成这一使用表单的应用程序，但我很新的语言，所以不100％作为我应该做的。

Hello I'm currently creating an application which has the need to add server IP addresses to it, as there is no InputBox function in C# I'm trying to complete this using forms, but am very new to the language so not 100% as to what I should do.

目前，我有我的主要形式和将作为我的输入框而想隐藏负载的形式。然后，当用户点击添加IP地址在主窗体上我想开拓二级形式返回的IP地址输入到二级窗体上的文本框。

At the moment I have my main form and a form which will act as my inputbox which wants to hide on load. Then when the user clicks on the add IP Address on the main form I wish to open up the secondary form and return the IP address entered into a text box on the secondary form.

所以，我怎么会去这样做？或者是还有什么更好的方法来达到类似的效果？

So how would I go about doing this? Or is there any better ways to achieve similar results?

推荐答案

在您的主要形式，添加事件处理该事件的按钮的点击添加IP地址。在事件处理程序，请执行以下代码类似：

In your main form, add an event handler for the event Click of button Add Ip Address. In the event handler, do something similar as the code below:

private string m_ipAddress;
private void OnAddIPAddressClicked(object sender, EventArgs e)
{
    using(SetIPAddressForm form = new SetIPAddressForm())
    {
        if (form.ShowDialog() == DialogResult.OK)
        {
            //Create a property in SetIPAddressForm to return the input of user.
            m_ipAddress = form.IPAddress;
        }
    }
}

修改：添加另外一个例子，以配合的 manemawanna 的意见

Edit: Add another example to fit with manemawanna comment.

private void btnAddServer_Click(object sender, EventArgs e)
{
    string ipAdd;
    using(Input form = new Input())
    {
        if (form.ShowDialog() == DialogResult.OK)
        {
            //Create a property in SetIPAddressForm to return the input of user.
            ipAdd = form.IPAddress;
        }
    }
}

在您输入的形式，添加属性：

In your Input form, add a property:

public class Input : Form
{
    public string IPAddress
    {
        get { return txtInput.Text; }
    }

    private void btnInput_Click(object sender, EventArgs e)
    {
        //Do some validation for the text in txtInput to be sure the ip is well-formated.

        if(ip_well_formated)
        {
            this.DialogResult = DialogResult.OK;
            this.Close();
        }
    }
}
