Triggering a button click through code
提问by Ralt
So I have the following code for when the "Add player" button is clicked
因此，当单击“添加播放器”按钮时，我有以下代码
private void addPlayerBtn_Click_1(object sender, EventArgs e)
{
//Do some code
}
I want to trigger this code from my SDK however. Here is what I have tried
但是，我想从我的 SDK 触发此代码。这是我尝试过的
private void command()
{
addPlayerBtn_Click_1(object sender, EventArgs e);
}
I get lots of errors as soon as I put in the line
我一排队就收到很多错误
addPlayerBtn_Click_1(object sender, EventArgs e)
Could somebody please tell me how to write the code so that I can trigger an event by just writting it in code?
有人可以告诉我如何编写代码，以便我只需将其写入代码即可触发事件吗？

For one, when calling a method, you don't declare the type of the parameter, just the value.
一方面，调用方法时，不声明参数的类型，只声明值。
So this:
所以这：
addPlayerBtn_Click_1(object sender, EventArgs e);
Should be
应该
addPlayerBtn_Click_1(sender, e);
Now, you'll have to declare senderand e. These can be actual objects, if you have event args to pass, or:
现在，您必须声明sender和e。这些可以是实际对象，如果您要传递事件参数，或者：
addPlayerBtn_Click_1(null, EventArgs.Empty);
The above can be used in either WinForms or ASP.NET. In the case of WinForms, you can also call:
以上可以在 WinForms 或 ASP.NET 中使用。在 WinForms 的情况下，您还可以调用：
addPlayerBtn.PerformClick();

When you call a function, you provide actual arguments, which are values, not formal arguments, which are types and parameter names.
当您调用函数时，您提供的是实际参数，即值，而不是形式参数，即类型和参数名称。
Change
改变
addPlayerBtn_Click_1(object sender, EventArgs e);
to
到
addPlayerBtn_Click_1(addPlayerBtn, EventArgs.Empty);
回答by gdoron is supporting Monica
addPlayerBtn_Click_1(object sender, EventArgs e);
Should be:
应该：
addPlayerBtn_Click_1(this, new EventArgs());
回答by ispiro
addPlayerBtn_Click_1(null, null);
This works if you don't need the information in senderand e.
如果您不需要sender和 中的信息，这将起作用e。
回答by Steve Wellens
You are not using the sender or the events so you can call the function directly like this:
您没有使用发送者或事件，因此您可以像这样直接调用该函数：
addPlayerBtn_Click_1(null, null);
回答by Majed Leader
private void command()
{
addPlayerBtn.PerformClick();
}
