Json 数组 - 检索 C# 中的第一条记录

Question

I am obtaining a JSON array in a dynamic object. How can I obtain the first item( equivalent of First for List collection)? How can I check if Json array is empty

Answer 1

If that's all you want to do with it, and if the underlying object implements IEnumerable , you could use:

foreach (dynamic item in array)
{
    // Use it here
    break;
}

Or use First explicitly:

dynamic first = Enumerable.First(array);
