How to check a specific string contains in the json object in core api

Hi

i have a function which will check given project name is include in the json object. For that I am not getting a proper json object in my response how to do that?

this is my object

{"projects":[{"name":"projects/sTest"},{"name":"projects/A345"},{"name":"projects/off"},{"name":"projects/dds"}]

What I have tried:

i have one main method which will call public bool CheckDuplicate(string name) method to return whether any same name inside the object or not.

 
public async Task UploadData(string name, string url)

{

var hasMatch = CheckDuplicate(name);

//post project_name methode here which will happen only hasmatch is false.need to block same names

}

public bool CheckDuplicate(string name)

{

string pname = name.Substring(9, name.Length - 9);

HttpClient client = new HttpClient();

client.BaseAddress = new Uri(httpRequest);

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

HttpResponseMessage response = client.GetAsync(httpRequest).Result;

var result = response.Content.ReadAsStringAsync().Result;

in result i am getting my objects like

{"projects":[{"name":"projects/sTest"},{"name":"projects/A345"},{"name":"projects/off"},{"name":"projects/dds"}]

var JSONObj = JsonConvert.DeserializeObject(result);

 
// i am getting values in JSONObj but below code is not working

//cant check the given pname is there or not

 
var hasMatch = false;

for (var index = 0; index < JSONObj.length; ++index)

{

var Projects = JSONObj[index];

if (Projects.name == pname)

{

hasMatch = true;

}

else

{

hasMatch = false;

}

}

return hasMatch;

}
