c# - 初始化字典 "on the fly"

Question

我有以下类(class)

public class PLCWrapper
{
    public int plc_id { get; set; }
    public List<SchakelingWrapper> schakelingWrapperList { get; set; }
    public Dictionary<string, string> globalVarDict { get; set; }
}

public class SchakelingWrapper
{
    public int schakeling_id { get; set; }
    public Dictionary<string, string> varDict { get; set; }
}

我想执行如下操作，但无法修复。当然有人知道怎么做？

if (plcWrapper.schakelingWrapperList.Exists(item => item.schakeling_id == id)) {
    plcWrapper.schakelingWrapperList.Single(item => item.schakeling_id == id).varDict.Add(varName, varValue);
} else {
    plcWrapper.schakelingWrapperList.Add(new SchakelingWrapper()
    {
        schakeling_id = id,
        varDict = new Dictionary<string, string>(varName, varValue)//This does not work
    });
}

Answer 1

它需要像...

varDict = new Dictionary<string, string>()
{
    {varname, varvalue}
}
