在C＃中更改字典值数组中的元素

Question

Say I have a Dictionary<int, string[]> dict . How could I change a specific element in a string[] in that dictionary, while keeping the others the same? I tried something like this

dict[0].ElementAt(0) = "Something Different";

but the left hand side isn't a variable/property/indexer.

Answer 1

ElementAt is a method that returns something, it is not the setter. You can use the array-indexer.

dict[0][0] = "Something Different";

Answer 2

ElementAt只是一个访问器，它不支持分配，您应该尝试直接索引访问，例如：

dict[0][0] = "Your String";
