DataStoreDataExtensions.ImportJson(this IDataStoreBase dataStore, string text) Method

.NET Standard 2.x

Inserts data from a JSON string into the DataStore.

Namespace: DWNet.Data

Assembly: DWNet.Data.dll

Syntax

 public static int ImportJson(this IDataStoreBase dataStore, string text);

Parameters

text System.String

A string specifying the JSON data.

The JSON string must comply with the plain-format JSON or DataWindow JSON.

Returns

System.Int32

Returns the number of rows that were imported if it succeeds.

Remarks

For plain-format JSON: It imports the JSON data to the primary buffer. For DataWindow JSON: It imports data from all of the buffers from the JSON string to the corresponding buffers and, if any, imports the data for DataWindowChild.

Examples

The following code example demonstrates how to import the department data from a JSON string to the DataStore.

using DWNet.Data;
using System;
using System.IO;

namespace Appeon.ApiDoc.DataStoreDataExtensionsExamples
{
    public class ImportJsonExample
    {
        private readonly SchoolContext _context;

        public ImportJsonExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example1()
        {
            // Instantiates the datastore with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            // Gets the JSON file
            string path = Path.Combine(AppContext.BaseDirectory,
                                @"Jsons\IDatastore\ImportJson1.json");
            string json = File.ReadAllText(path);

            // Imports data from JSON to DataStore
            datastore.ImportJson(json);

            Console.WriteLine("Rowcount: {0}", datastore.RowCount);

            /*This code produces the following output:

            Rowcount: 2
           */
        }
    }
}
