C＃foreach循环仅在整个json文件中显示2个结果
我需要JSON文件中的每个玩家名字和姓氏在数据网格视图中填充。一切都很好，除了我在dgv中只有2名玩家。这两名球员都是在json的预期部分之后，所以只有2名球员为我展示了＃34; Marcus Smart＆＃34;和＆＃34; Cedi Osman＆＃34;。
CODE：
public void StartingLineups()
{
upass.upass up = new upass.upass();
string address3 = "https://api.mysportsfeeds.com/v1.1/pull/nba/2017-2018-regular/game_startinglineup.json?gameid=" + dateTimePicker1.Text + comboBox2.Text;
var w3 = new WebClient();
w3.UseDefaultCredentials = true;
w3.Credentials = new NetworkCredential(up.username, up.password);
var result3 = w3.DownloadString(address3);
var obj3 = JObject.Parse(result3);
dt.Columns.Add("Projected Lineup", typeof(string));
StartingLineup.startinglineup sl = new StartingLineup.startinglineup();
foreach (JObject child in obj3["gamestartinglineup"]["teamLineup"])
{
sl.expected = child["expected"]["starter"][0]["player"]["FirstName"].ToString() + " " + child["expected"]["starter"][0]["player"]["LastName"].ToString();
DataRow row = dt.NewRow();
dataGridView1.DataSource = dt;
row["Projected Lineup"] = sl.expected;
dt.Rows.Add(row);
}
}

3 个答案:
答案 0 :(得分：3)
你在timelineup元素上的循环不足以列出你团队中的玩家。你需要一个内循环
foreach (JObject child in obj3["gamestartinglineup"]["teamLineup"])
{
foreach (JObject sub in child["expected"]["starter"])
{
var expected = sub["player"]["FirstName"].ToString() + " " + sub["player"]["LastName"].ToString();
DataRow row = dt.NewRow();
row["Projected Lineup"] = expected;
dt.Rows.Add(row);
}
}
也不要在循环内为gridview分配数据源，但只有当你完成阅读所有内容时
答案 1 :(得分：2)
你在错误的地方使用你的foreach
foreach (JObject child in obj3["gamestartinglineup"]["teamLineup"])
在这部分代码中，循环只包含2个项目！
以及＆＃34; Marcus Smart＆＃34;和＆＃34; Cedi Osman＆＃34;是每个
的第一个玩家 
纠正你的foreach循环以解决问题
答案 2 :(得分：2)
你的foreach循环正在循环通过团队阵容为游戏阵容。该阵容中只有两支球队。然后你只抓住每支球队中的第一名球员。相关的代码行是
foreach (JObject child in obj3["gamestartinglineup"]["teamLineup"])
{
sl.expected = child["expected"]["starter"][0]["player"]["FirstName"].ToString() + " " + child["expected"]["starter"][0]["player"]["LastName"].ToString();
child["extected"]["starter"][0]["player"]这个名称只为你提供了这两支队伍中的第一个首发球员。
如果你想获得每支球队的所有首发球员，你必须在第一支球队中添加第二个foreach循环，就像这样......
foreach (JObject child in obj3["gamestartinglineup"]["teamLineup"])
{
foreach (JObject player in child["expected"]["starter"])
{
