problem in total up the value

[ashley11]

i have a problem to sum up the value.
for example:
in my richtextbox1:
0.94
0.83
1.67
0.50
0.67
1.25
0.98

now i wan to total up the value.
if the value is less than 1 , then total is 5.
if the value is greater than 1, then total is 2.
below are my coding, but cannot work.

  int count = 0;

        double liftV = richTextBox24.Lines.Length;

        if (liftV <1.00)
        {
            count++;


        }
        textBox5.Text=count.ToString();

hope someone can help me..

Code to sum up

//Your Code
double sum=0;
int length=richTextBox1.Lines.Length;
for(int i=0;i<length;i++)
{
sum+=Double.Parse(richTextBox1.Lines[i]);
}
if(sum<1)
{
//Your Code
}
else 
{
//Your Code
}
//Your Code

[abelLazm]

//Your Code
double sum=0;
int length=richTextBox1.Lines.Length, totalGreater=0, totalsmaller=0;
for(int i=0;i<length;i++)
{
//sum+=Double.Parse(richTextBox1.Lines[i]);
if(Double.Parse(richTextBox1.Lines[i])>=1)
totalGreater++;
else
totalSmaller++;

}
MessageBox("Total values less than 1 are:"+totalSmaller+"\n Total values greater than equal to 1 are:"+totalGreater);
//Your Code

i had try your code, but it show me a error which is input string was not in a correct format.
may i know any wrong that i did?

[abelLazm]

This Code is Working Fine.... Check the input you are giving in the richTextBox1

double sum = 0;
                 int length =   richTextBox1.Lines.Length, totalGreater = 0, totalSmaller = 0;
                 for (int i = 0; i < length; i++)
                 {
                     //sum+=Double.Parse(richTextBox1.Lines[i]);
                     if (Double.Parse( richTextBox1.Lines[i]) >= 1)
                         totalGreater++;
                     else
                         totalSmaller++;

                 }
                 MessageBox.Show("Total values less than 1 are:" + totalSmaller + "\n Total values greater than equal to 1 are:" + totalGreater);
                 //Your Code

string b = txtTotalItems.Text;
            double tt = Double.Parse(b);
            double a;
            double conf;
            double lift;

            richTextBox23.Clear();
            richTextBox24.Clear();
            richTextBox20.Clear();

            for (int i = 0; i < list8.Count; i++)
            {
                double wee = list8[i];
                a = (wee / tt) * 100;
                richTextBox3.AppendText(string.Format("{0:n2}", a) + "\n");

                double SuppA = list9[i];
                conf = a / (SuppA / tt);
                richTextBox2.AppendText(string.Format("{0:n2}", conf) + "\n");

                double SuppB = list10[i];
                lift = conf / (SuppB / tt) / 100;
                richTextBox1.AppendText(string.Format("{0:n2}", lift) + "\n");

code above are my calculation part. now i wan to sum up the total in the rich textBox1.
when i try your coding, then show me the error which i mentioned just now. how to i correct it?

[abelLazm]

can you please tell where you want to add the above mentioned code?

[ashley11]

string b = txtTotalItems.Text;
            double tt = Double.Parse(b);
            double a;
            double conf;
            double lift;

            richTextBox23.Clear();
            richTextBox24.Clear();
            richTextBox20.Clear();

            for (int i = 0; i < list8.Count; i++)
            {
                double wee = list8[i];
                a = (wee / tt) * 100;   
                richTextBox3.AppendText(string.Format("{0:n2}", a) + "\n");

                double SuppA = list9[i];
                conf = a / (SuppA / tt);
               
                richTextBox2.AppendText(string.Format("{0:n2}", conf) + "\n");

                double SuppB = list10[i];
                lift = conf / (SuppB / tt) / 100;
                
                richTextBox1.AppendText(string.Format("{0:n2}", lift) + "\n");
            }

            double sum = 0;
            int length = richTextBox24.Lines.Length, totalGreater = 0, totalSmaller = 0;
            for (int i = 0; i < length; i++)
            {
                //sum+=Double.Parse(richTextBox1.Lines[i]);
                if (Double.Parse(richTextBox24.Lines[i]) >= 1)
                    totalGreater++;
                else
                    totalSmaller++;

            }
            MessageBox.Show("Total values less than 1 are:" + totalSmaller + "\n Total values greater than equal to 1 are:" + totalGreater);
        }

may i know any mistake with it?

}

may i know any mistake with it?

[abelLazm]

in line# 30 run the loop to i<length-1 because you append "\n" at the end that is why your last item in the richTextBox1 is an empty string which is causing error

Apart from the Point said by abelLazm remaining all is fine, i checked it out.

[ashley11]

thanks. i get it.
