body: <p>I am new to json format. I want to create a following json string by using C# and json.net package.</p>
  
  <p>This is my target Json format:</p>
  
  <pre><code>{
    "GetQuestions": 
    {
      "s1":"Q1,Q2",
      "s2":"Q1,Q3",
      "s3":"Q4,Q5"
    }
  }
  </code></pre>
  
  <p>Here, i am storing each students questions.But sometimes, the total number of students may be vary.for example it may be s1,s2 only or s1,s2,s3,s4.... This is calculated at runtime in C#.So, i want to create the json string depending on the student list....</p>
