我正在尝试阅读我的JSON结果.

这是我的RootObject

public class RootObject
{
public int id { get; set; }
public bool is_default { get; set; }
public string name { get; set; }
public int quantity { get; set; }
public string stock { get; set; }
public string unit_cost { get; set; }
}

这是我的JSON结果

[{"id": 3636, "is_default": true, "name": "Unit", "quantity": 1, "stock": "100000.00", "unit_cost": "0"}, {"id": 4592, "is_default": false, "name": "Bundle", "quantity": 5, "stock": "100000.00", "unit_cost": "0"}]

这是我读取结果的代码

     public static RootObject GetItems(string user, …

我是Gradle Spring应用程序的新手.运行我的项目根据我创建的类创建数据库对象,我收到以下错误:

我有这个代码块读取文本文件[Tab分隔]并返回一个数据表.但问题是它将文件或记录的第一行视为标题,并将剩余的行显示为记录,减去记录的数量 - 1所以现在我希望代码将文件的所有内容读作记录.

这是代码:

streamReader reader = new streamReader (filePath);
string line = reader.readLine();
Datatable dt = new Datatable ();
DataRow row;
string[] value = line.Split('\t');

foreach(string dc in value)
{
 dt.columns.add(New DataColumn(dc));
}

while(!reader.endofStream)
 {
  value = reader.ReadLine().split('\t');

  if (value.Length == dt.Columns.Count)
 {
  row = dt.NewRow();
  row.ItemArray = value;
  dt.Rows.Add(row);
 }

 }

 return dt;

当我试图删除

foreach(string dc in value)
{
 dt.columns.add(New DataColumn(dc));
}

和所有依赖它的行代码,dt什么都不返回.

我怎么解决呢？
