"description": "In 2003, USAID committed to providing emergency diesel-generated power to the key southern cities of Kandahar (Kandahar Province), Lashkar Gah (Hilmand Province), and Qalat (Zabul Province). The World Bank provides emergency diesel generators to eight provincial cities, including Aybak (Samangan Province), Musa Qala (Hilmand Province), and Tirin Kot (Uruzgan Province). Providing diesel power to these areas was a short-term way to provide immediate sources of electrical while longer-term and more sustainable lower-cost solutions were being developed. The delay in longer-term solutions and the changing reality over the past four years makes it clear that the temporary diesel power stations must be converted to permanent installations. In addition, the stations have been in use for much longer than initially planned, requiring continued operations and maintenance support. USAID is continuing to provide technical support and is developing the capacity of Da Afghanistan Breshna Sherkat (Afghanistan National Electricity Corporation ? DABS) to manage these power plants.",

"description": "Afghanistan's public electricity sector lacks adequate levels of human resources and organization. The Government of the Islamic Republic of Afghanistan and the international community have invested hundreds of millions of dollars to develop and build a wide variety of projects to improve electricity supply. One major project for increasing the power supply to Kabul is the North-East Power System, supported by many stakeholders and donors. To bring together the various ministries that have an impact on the electric power sector, the government created the Inter-Ministerial Commission for Energy (ICE) and appointed a secretariat to support it. The government also created a working group to support the Ministry of Energy and Water. The objective of this USAID-funded project is to provide long-term technical assistance and support through advisors to the ICE Secretariat. Advising the ICE involves a multi-disciplined, multi-pronged approach within the Afghan government and the donor community to produce positive and sustainable results. The Asian Development Bank, USAID, the World Bank, GIZ (a federally owned organization supporting the German Government in achieving its development objectives), and other donors provide technical advisors. Together, these advisors provide inputs to the ICE Secretariat to develop solutions in their areas of responsibilities and expertise."

But i want to filter this json dynamically based on key and values in Dot net core.

 I have used following code to pares the response

 

string responseString = await GetAppendUrlResponseString(httpResponseMessage);

var json = JArray.Parse(responseString);

JArray array = new JArray();

string url = baseUrlRequestModel.AppendUrl;

var keyValues = url.Split('?');

var parts1 = keyValues[1].Split('&');

 

foreach (var item in json)

{

for (int i = 0; i < parts1.Length; i++)

{

var SS = parts1[i].Split('=');

if ((string)item[SS[0]].Value<string>() == SS[1])

{

responseString = Convert.ToString(item);

}

else

{

responseString = "";

}

}

if(responseString!="")

array.Add(responseString);

}

But when response filtering it will throws error due to Projects objcts without objects it will run finebut with objects it will through exception.

 

Note: That objects get dynamically Now are Projects, Sometimes it may be list, it may be Users so dont know it is randomly reading json
