海伊..。我现在正面临困境。
我需要开发一个程序,其中一个功能是它可以将JSON文件转换成CSV文件。
我现在拥有的是:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.IO;
using Aspose;
using Aspose.Cells;
namespace WpfApplication1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
string str = File.ReadAllText(@"C:\cpi\log\V510ResultsInfo\cpi001.json");
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
Aspose.Cells.Cells cells = workbook.Worksheets[0].Cells;
Aspose.Cells.Utility.JsonLayoutOptions importOptions = new
Aspose.Cells.Utility.JsonLayoutOptions();
importOptions.ConvertNumericOrDate = true;
importOptions.ArrayAsTable = true;
importOptions.IgnoreArrayTitle = true;
importOptions.IgnoreObjectTitle = true;
Aspose.Cells.Utility.JsonUtility.ImportData(str, cells, 0, 0, importOptions);
workbook.Save(@"C:\cpi\log\V510ResultsInfo\convertedjson.csv");
}
}
}问题是'Aspose.Cells.Utility'中的‘实用程序’。我一直在网上搜索,但这似乎没什么大不了的。
我只知道“Aspose.Cells.Utility.JsonLayoutOptions”位于Aspose.Cells.dll中的“Aspose.Cells.Utility”命名空间中。DLL没什么问题一切都很好..。只是错误仍然存在:
错误消息:名称空间'Aspose.Cells‘中不存在类型或名称空间名称'Utility’(您缺少程序集引用吗?)

除了jayrag提供的答案之外,我想说的是,Apsose.Cells.Utility似乎是一个较新的名称空间,因此它不能用于早期版本的Aspose。我只是检查了它的版本17,在那里,它肯定是不可用的。我在Aspose.Cells中也找不到任何可以帮助您的替代方法。简单地说,json支持似乎还很新,要使用它,您需要升级许可证。考虑到阿什的价格,你也许应该去做个调整。希望这能帮点忙。干杯!

我认为您不需要Aspose来创建csv,尝试如下:
private void Button_Click(object sender, RoutedEventArgs e)
{
string json = File.ReadAllText(@"C:\cpi\log\V510ResultsInfo\cpi001.json");
var model = JsonConvert.DeserializeObject<MyModel>(json, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
InsertRecordInCsv(model, "convertedjson");
}
public static void InsertRecordInCsv<T>(T model, string fileName)
{
string targetFolder = @"C:\cpi\log\V510ResultsInfo\";//fileSaveFolderName
if (!Directory.Exists(targetFolder))
{
Directory.CreateDirectory(targetFolder);
}
string targetPath = Path.Combine(targetFolder, fileName + ".csv");
if (!File.Exists(targetPath))
{
var fs = new FileStream(targetPath, FileMode.Create);
fs.Close();
string csvHeader = string.Empty;
foreach (PropertyInfo info in typeof(T).GetProperties())
{
csvHeader += (!string.IsNullOrEmpty(csvHeader) ? "," : string.Empty) + info.Name;
}
csvHeader += Environment.NewLine;
File.AppendAllText(targetPath, csvHeader);
}
StringBuilder sbData = new StringBuilder();
string csvModel = string.Empty;
foreach (PropertyInfo info in typeof(T).GetProperties())
{
string value = GetPropValue(model, info.Name) != null ? GetPropValue(model, info.Name).ToString() : string.Empty;
sbData.Append("\"" + value.Replace("\"", "\"\"") + "\",");
}
sbData.Replace(",", Environment.NewLine, sbData.Length - 1, 1);
File.AppendAllText(targetPath, sbData.ToString());
}
public static object GetPropValue(object src, string propName)
{
if (src.GetType().GetProperty(propName) != null)
return src.GetType().GetProperty(propName).GetValue(src, null);
return new object();
