c# - 将字典分配给键值

Question

Dictionary<int, String> loadData = new Dictionary();

// File contains a list of filenames say for ex. 5 filenames
foreach (var file in filenames)
{
    // I want to assign like this
    loadData[id]=file;
}

如何分配 loadData(key,value)在 C# 中，这样我就可以访问 loadData[5] = "hello.txt" ;

Answer 1

首先:您正在使用new Dictionary()这将无法正常工作。使用new Dictionary<int, String>()相反。

第二: id 在哪里来自？如果它只是一个计数器，您可以执行以下操作:

Dictionary<int, String> loadData = new Dictionary<int, String>();
int id = 0;
foreach (string file in filenames)
{
   loadData.Add(id++, file);
}
