我不知道如何将包含多个项目的字典添加到另一个字典作为值
Dictionary<string,Dictionary<string,double>> proptest=new Dictionary<string,Dictionary<string,double>>
if (proptest.ContainsKey(filenametest))
{
proptest[filenametest].Add(filenametraining, NB) ;
}
else
{
proptest.Add(filenametest, new Dictionary<string, double> { { filenametraining, NB } });
}
结果是: {[10171.txt,System.Collections.Generic.Dictionary`2 [System.String,System.Double]]} 虽然我想要的结果是: {[10171.txt:(cat10 0.4)(cat3 0.6)]}
答案 0 :(得分:0)
您可以添加如下现有词典:
// The 'outer' dictionary:
var myDictionary = new Dictionary<string, Dictionary<string, double>>();
// an existing 'inner' dictionary:
var innerDictionary1 = new Dictionary<string, double> {
{ "inner1.1", 6 }, { "inner1.2", 4.5 }
};
// add the inner to the outer:
myDictionary.Add("outer1", innerDictionary1);
要内联添加'内部'字典:
myDictionary.Add("outer2",
new Dictionary<string, double> {
{ "inner2.1", 3.48748}, { "inner2.2", 25 }, { "inner2.3", 0 }
});
此外,如果要将值添加到内部字典,可以执行以下操作:
myDictionary["outer2"].Add("inner2.4", 3.56);
