字典查找-特定字符串

本文关键字：字符串 查找 字典 | 更新日期: 2023-09-27 17:53:07

我想在512个dmx通道中控制一种颜色(在这个例子中是"红色")。我从xml文件中读取红色并将其放入Dictionary中:

<Channel Id="Lamp1Red" Key="2"/>
<Channel Id="Lamp1Green" Key="3"/>
<Channel Id="Lamp1Blue" Key="4"/>
<Channel Id="Lamp2Red" Key="5"/>
<Channel Id="Lamp2Green" Key="6"/>
<Channel Id="Lamp2Blue" Key="7"/>
<Channel Id="Lamp3Red" Key="8"/>
        etc. ... up to 512 keys/channels.

我有以下Dictionary，其中包含id(字符串)和通道(键+值)

public Dictionary<string, Tuple<byte, byte>> DmxChannelsDictionary
{
    get;
    set;
}

我想查找包含ID"LampXRed"的所有字符串(红色)，并获得每个字符串的键(2,5,8)，并在以下方法SetColor中使用它们:

SetColor(red, green, blue);
public void SetColor(Tuple<byte, byte> redTuple, Tuple<byte, byte> greenTuple, Tuple<byte, byte> blueTuple)

SetColor将元组传递给DmxDataMessage()

public static byte[] DmxDataMessage(Tuple<byte, byte>  redTuple, Tuple<byte, byte> greenTuple, Tuple<byte, byte> blueTuple)
    {
        //Initialize DMX-buffer: Must be full buffer (512Bytes)
        var dmxBuffer = new byte[512];
        dmxBuffer.Initialize();
        // Fill DATA Buffer: Item1 (Key/Channel) = Item2 (Value)
        // Channel1
        dmxBuffer[redTuple.Item1] = redTuple.Item2;
        dmxBuffer[greenTuple.Item1] = greenTuple.Item2;
        dmxBuffer[blueTuple.Item1] = blueTuple.Item2;
        // Here I need a foreach or something else to set the the value for each channel (up to 512)
       ....

我如何在字典中进行智能搜索/交互并保存所有红色id +键以供SetColor()使用??

对于一个"红色"通道，我是这样做的:

var red = DmxChannelsDictionary["Lamp1Red"];
red = Tuple.Create(red.Item1, _redValue); // _redValue = 0-255

我希望这有意义。非常感谢你的帮助!

字典查找-特定字符串

为什么不这样呢:

class LampInfo
{
  int Red{get;set;}
  int Green{get;set;}
  int Blue{get;set;}
}

，然后将灯名(例如Lamp1)映射到它:

Dictionary<string,LampInfo> dmxChannelsDictionary;

要填充，您可以这样做:

那么你可以这样做:

Lamp lamp=new LampInfo(){Red=2, Green=3, Blue=4}'
dmxChannelsDictionary.Add("Lamp1",lamp);

然后你只需要输入:

var lamp=dmxChannelsDictionary["Lamp1"];
int red=lamp.Red;

下面修复了我的问题-非常感谢您的帮助。

public static byte[] DmxDataMessage(Tuple<byte, byte> redTuple, Tuple<byte, byte> greenTuple, Tuple<byte, byte> blueTuple, EnttecDmxController _enttecDmxControllerInterface)
{
    foreach (KeyValuePair<string, Tuple<byte, byte>> entry in _enttecDmxControllerInterface.DmxChannelsDictionary)
    {
        if (entry.Key.Contains("Red"))
        {
            dmxBuffer[entry.Value.Item1] = redTuple.Item2;
        }
    }
     .......
}
