我在让EventHandler
为多个按钮工作时遇到了一些困难。他们将执行相同的工作,即链接到相同的表单(ModuleTemplate
),并使用与该模块相关的适当内容填充它。
我只粘贴了有问题的代码。它编译得很好,第一个按钮(btnAudioNotetaker)工作正常,其他按钮什么都不做。
public void createAudioNotetaker()
{
//this button click event works
btnAudioNotetaker.Click += new EventHandler((sender, e) => btnModule_Click(sender, e, audioNotetakerDict, videoPathDict, pdfPathDict, audioPathDict));
}
public void createClaroRead()
{
//this one doesn't work
btnClaroRead.Click += new EventHandler((sender, e) => btnModule_Click(sender, e, audioNotetakerDict, videoPathDict, pdfPathDict, audioPathDict));
}
void btnModule_Click(object sender, EventArgs e, OrderedDictionary pageContent, OrderedDictionary videoPathDict, OrderedDictionary pdfPathDict, OrderedDictionary audioPathDict)
{
//i want to use this event for each button
ModuleTemplate newForm = new ModuleTemplate(pageContent, videoPathDict, pdfPathDict, audioPathDict);
newForm.Show();
this.Hide();
}

Lambdas很酷,但我觉得这段代码更清晰。它可能会或可能不会解决您的问题(尝试此代码时可能会遇到编译器错误),但维护起来会更容易。
public void createAudioNotetaker()
{
//this button click event works
btnAudioNotetaker.Click += commonClickHandler;
}
public void createClaroRead()
{
//this one doesn't work
btnClaroRead.Click += commonClickHandler;
}
void commonClickHandler(object sender, EventArgs e)
{
btnModule_Click(sender, e, audioNotetakerDict, videoPathDict, pdfPathDict, audioPathDict));
}
void btnModule_Click(object sender, EventArgs e, OrderedDictionary pageContent, OrderedDictionary videoPathDict, OrderedDictionary pdfPathDict, OrderedDictionary audioPathDict)
{
//i want to use this event for each button
ModuleTemplate newForm = new ModuleTemplate(pageContent, videoPathDict, pdfPathDict, audioPathDict);
newForm.Show();
this.Hide();
}

我的错误,正如上面的评论所示,我没有在我的switch和case语句中调用我的createClaroRead函数。这种愚蠢的事情要忽视。
感谢大家的回复。
