.net 把下面字符串数据的首尾去除空格 并 转换为json数组

假设字符串数据为：

string data = "   [  1, 2 ,  3 ,4]   ";

可以使用以下代码实现要求：

using System;
using System.Text.Json;

class Program
{
    static void Main(string[] args)
    {
        string data = "   [  1, 2 ,  3 ,4]   ";
        data = data.Trim(); // 去除首尾空格
        var jsonArray = JsonSerializer.Deserialize<int[]>(data); // 转换为 int 数组
        string json = JsonSerializer.Serialize(jsonArray); // 转换为 json 字符串
        Console.WriteLine(json);
    }
}

输出结果为：

[1,2,3,4]

json空的字符串怎么判断

判断一个 JSON 字符串是否为空，可以通过以下两种方法：

1. 使用 Python 内置的 json 库进行解析，然后判断解析后的结果是否为空：

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
parsed_json = json.loads(json_str)

if not parsed_json:
    print("JSON 字符串为空")

2. 直接判断字符串本身是否为空：

json_str = '{}'

if not json_str.strip():
    print("JSON 字符串为空")

其中，`strip()` 方法可以去除字符串首尾的空白字符，包括空格、制表符、换行符等。
