public static JsonDataSource CreateDataSourceFromFile() {
    var jsonDataSource = new JsonDataSource();
    // Specify the JSON file name.
    Uri fileUri = new Uri("customers.json", UriKind.RelativeOrAbsolute);
    jsonDataSource.JsonSource = new UriJsonSource(fileUri);
    // Populate the data source with data.
    jsonDataSource.Fill();
    return jsonDataSource;
}

VB.NET

Imports DevExpress.DataAccess.Json
' ...
Public Shared Function CreateDataSourceFromFile() As JsonDataSource
    Dim jsonDataSource = New JsonDataSource()
    ' Specify the JSON file name.
    Dim fileUri As New Uri("customers.json", UriKind.RelativeOrAbsolute)
    jsonDataSource.JsonSource = New UriJsonSource(fileUri)
    ' Populate the data source with data.
    jsonDataSource.Fill()
    Return jsonDataSource
