如何更改比UI线程更多的另一个线程的TextBox.text（使用相同的功能）？

Question

我的问题是改变大量的另一个线程的TextBox.text比UI线程。 像这样：

string bufferSerial; 
. 
. 
. 
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) 
{ 
    bufferSerial += serialPort1.ReadLine(); 
    TextBox1.text = bufferSerial; 
    TextBox2.text = bufferSerial; 
    TextBox3.text = bufferSerial; 
    TextBox4.text = bufferSerial; 
    TextBox5.text = bufferSerial; 
    TextBox6.text = bufferSerial; 
    TextBox7.text = bufferSerial; 
. 
. 
. 
. 
. 
. 
    TextBoxN.text = bufferSerial; 
} 

如果我试图做到这一点我有一个错误：控制“textBox1的”从比它创建的线程以外的线程访问。

要改变一个文本框，我可以使用此解决方案：

delegate void SetTextCallback(string text); 

private void SetText(string text) 
{ 
    // InvokeRequired required compares the thread ID of the 
    // calling thread to the thread ID of the creating thread. 
    // If these threads are different, it returns true. 
    if (this.textBox1.InvokeRequired) 
    { 
    SetTextCallback d = new SetTextCallback(SetText); 
    this.Invoke(d, new object[] { text }); 
    } 
    else 
    { 
    this.textBox1.Text = text; 
    } 
} 

，然后调用这样的功能：

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) 
{ 
    bufferSerial += serialPort1.ReadLine(); 
    SetText(bufferSerial); 
} 

但是，如果我需要改变很多BoxText我有为每一个创建一个函数？

谢谢你的帮忙！ 此致敬礼。

否，创建一个方法，它改变了文本框的所有 - 并援用：

// We assume this will always be called from a non-UI thread... 
private void HandleDataReceived(object sender, SerialDataReceivedEventArgs e) 
{ 
    bufferSerial += serialPort1.ReadLine(); 
    Action<string> d = SetAllTextBoxes; 
    Invoke(d, bufferSerial); 
} 

private void SetAllTextBoxes(string text) 
{ 
    textBox1.Text = text; 
    textBox2.Text = text; 
    textBox3.Text = text; 
    textBox4.Text = text; 
    ... 
} 

理想情况下，你不得不文本框集合中，所以你可以把它改写为：

private void SetAllTextBoxes(string text) 
{ 
    foreach (var textBox in textBoxes) 
    { 
     textBox.Text = text; 
    } 
}
