你也可以在文本字符串中使用这个变体，这里是完整的更改代码(来自Mikael的代码)，在c# 2012中测试:

// Variable
string MessageBoxTitle = "Some Title";
string MessageBoxContent = "Sure";

DialogResult dialogResult = MessageBox.Show(MessageBoxContent, MessageBoxTitle, MessageBoxButtons.YesNo);
if(dialogResult == DialogResult.Yes)
{
    //do something
}
else if (dialogResult == DialogResult.No)
{
    //do something else
}

你可以

.YesNo

插入消息图标

, MessageBoxIcon.Question

这个简单的代码对我很有用。我从MSDN上下载的:

if (System.Windows.Forms.MessageBox.Show
            ("Are you sure you want to add the audit?", "Add",
            System.Windows.Forms.MessageBoxButtons.YesNo, 
            System.Windows.Forms.MessageBoxIcon.Question)
            ==System.Windows.Forms.DialogResult.Yes)                
        // Do stuff after 'YES is clicked'
        else
        // DO stuff after 'NO is clicked'

Use:

MessageBoxResult m = MessageBox.Show("The file will be saved here.", "File Save", MessageBoxButton.OKCancel);
if(m == m.Yes)
{
    // Do something
}
else if (m == m.No)
{
    // Do something else
}

在Windows Phone上使用MessageBoxResult而不是dialgresult…

试试这个:

if (MessageBox.Show("Are you sure", "Title_here", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
{
    Do something here for 'Yes'...
}

这应该做到:

DialogResult dialogResult = MessageBox.Show("Sure", "Some Title", MessageBoxButtons.YesNo);
if(dialogResult == DialogResult.Yes)
{
    //do something
}
else if (dialogResult == DialogResult.No)
{
    //do something else
}
