Question

I’m a beginner in C# so please be gentle to me .

I’m having a problem trying to display more results in rich text box because it can only display one result at once. But I would like to display the next result when the radio buttons already being resetted and the previous result should also still in the rich text box. Below is my coding:

for(int i=0,i<30;i++)
{
  if(symptom1.Checked && symptom2.Checked)
  {
     Result.Text="";
     Result.Text += "Your Disease is: "+"Meningiomas";
  }

  if(symptom7.Checked && symptom8.Checked)
  {
     Result.Text="";
     Result.Text += "Your Disease is: "+"Pituitary Tumor";
  }
}

Answer 1

If you don’t want to delete the previous content, remove this code:

Result.Text="";

I think, what you want to achieve is:

1. Clear the RichTextBox
2. Write all matching diseases to the RichTextBox

This can be done with this code:

Result.Text="";

for(int i = 0; i < 30; ++i)
{
    if(symptom1.Checked && symptom2.Checked)
    {
        Result.Text += "Your Disease is: "+"Meningiomas";
    }

    if(symptom7.Checked && symptom8.Checked)
    {
        Result.Text += "Your Disease is: "+"Pituitary Tumor";
    }
}
