你好，我目前正在創建具有需要服務器的IP地址添加到它，因爲在C＃中沒有InputBox函數我試圖完成這個使用表單的應用程序，但我非常新的語言，所以不是我應該做的100％。創建使用表單
目前我有我的主窗體和一個窗體，它將充當我的輸入框，它想要加載隱藏。然後，當用戶點擊主窗體上的添加IP地址時，我希望打開輔助表單並將輸入的IP地址返回到輔助表單上的文本框中。
那麼我該怎麼做呢？或者有沒有更好的方法來達到類似的結果？
在主窗體，添加事件處理程序的事件按鈕的點擊添加IP地址。在事件處理程序，請執行以下代碼類似：
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;
}
}
}
編輯：添加另一個例子，以配合manemawanna評論。
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;
}
}
}
在你輸入的形式，添加屬性：
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();
}
}
}
您應該更好地使用using（）語句。 :) – 2009-07-18 12:39:40
好了，我們每一天:)學習的東西，我申請使用關鍵字在我的代碼上的一切（筆，SqlConnection的，流等），但我從來沒那麼一個形式。可能是因爲我從來沒有見過一個應用它的例子......甚至在一本書中。 – 2009-07-18 13:01:35
在主窗體中添加一個按鈕。
爲ip地址創建一個帶有文本框的表單。 （可以說IPAddressForm）
爲該按鈕添加單擊事件處理程序。
在事件處理程序中，創建一個IPAddressForm的實例並調用IPAddressForm的showdialog方法。
將IP地址存儲在某個類變量中。
如果ShowDialog的結果是正確的，閱讀的主要形式類變量（最簡單的方法是聲明字段作爲公共）
看起來像弗朗西斯有正確的想法是什麼，我會建議。然而，僅僅添加到這一點，我可能會建議使用MaskedTextBox中，而不是一個基本的文本框，並添加IP地址格式的面具。
你可以只使用VB的InputBox ......
我需要這個功能了。這是我的代碼;它自動中心和大小，以適應提示。公共方法創建一個對話框並返回用戶的輸入，如果它們被取消，則返回null。

，並在主應用程序調用，比如：
