將字符串的值轉換為KeyValuePair的變量<TKey,TValue>

Question

我做的是這樣的：

foreach( KeyValuePair<int,SOME_CLASS> reader in _readerDict )
{
  var selectedReader = reader;

  var antenna1 = selectedReader.Value.Antenna1IsEnabled;
  var antenna2 = selectedReader.Value.Antenna2IsEnabled;
  var antenna3 = selectedReader.Value.Antenna3IsEnabled;
  var antenna4 = selectedReader.Value.Antenna4IsEnabled;
}

但是我又要做以下事情：

foreach( KeyValuePair<int,SOME_CLASS> reader in _readerDict )
{
  var selectedReader = reader;

  for( var idx = 1; idx <= 4; idx++ )
  {
    var antennaIsEnabled = string.Format( "selectedReader.Value.Antenna{0}IsEnabled", idx );

    // cast the value of antennaIsEnabled as a KeyValuePair<int,SOME_CLASS> variable datatype here
    ....
  }
}

反正我是否將antennaIsEnabled的值轉換為KeyValuePair變量數據類型？

Answer 1

我想你要提取的selectReader關鍵和AntennaIsEnabled作為價值

string[] parts = strA.Split('.');
var list = new List<KeyValuePair<string, string>>();
list.Add(new KeyValuePair<string, string>(part[0], part[2]));

需要添加一些錯誤檢查...

Answer 2

聽起來你想要一個看起來像這樣的結果：

Dictionary<int, bool> AntennaIsEnabled = new Dictionary<int, bool>();
foreach( KeyValuePair<int,SOME_CLASS> reader in _readerDict )
{
  var selectedReader = reader;

  //From your example
  AntennaIsEnabled.Add(1, selectedReader.Value.Antenna1IsEnabled);
  AntennaIsEnabled.Add(2, selectedReader.Value.Antenna2IsEnabled);
  AntennaIsEnabled.Add(3, selectedReader.Value.Antenna3IsEnabled);
  AntennaIsEnabled.Add(4, selectedReader.Value.Antenna4IsEnabled);
}

然后，您可以使用AntennaIsEnabled [2]等語法訪問每個天線的狀態。

嘗試使用FastMember庫以字符串形式訪問您的屬性。
