上記の数行を取得したキーを使用しているにもかかわらず、何らかの理由で KeyNotFoundException を取得している次のコードがあります。これがうまくいかない状況を知っている人はいますか?私は困惑しています。ところで 'SchemaElementType は列挙型です。
public class DefaultValue
{
private Dictionary<Parameter, string> _params;
public DefaultValue(Dictionary<Parameter, string> parameters)
{
_params = parameters;
}
public string GetParameterValue(string name)
{
foreach(Parameter param in _params.Keys)
{
if(param.ParamName.Equals(name))
{
// **** Issue here ****
return _params[param];
}
}
return string.Empty;
}
}
