C# condition that works outside of method-CodePudding

                        double positions = Convert.ToDouble(textBox2.Text);
 

                        if (textBox3.Text == "Long")
                        {
                            positions = positions;
                            

                        }if (textBox3.Text == "Short")
                        {
                            positions = positions * -1;
                            
                        }

Is there any other way I can use a condition where if the textbox3 says "Long" it will convert position to and if it says "Short" converts the position number to negative. I don't want to use if statement because it creates two different blocks of code. I just want one block.

For example: if textbox3 is Long or short: convert position to negative or positive, then I'm able to use position in a method below.

How about an inline if statement ?

positions = textBox3.Text == "Long" ? positions :   positions * -1;

This will only work if there are only two possible values for textBox3.Text

CodePudding user response：

you can initiate positions with inline if statement :

double positions =  textBox3.Text == "short" ? 
Convert.ToDouble(textBox2.Text) * (-1) : 
Convert.ToDouble(textBox2.Text);

if you want do something else when textBox3.Text == "Long" :

double positions =  textBox3.Text == "short" ? 
Convert.ToDouble(textBox2.Text) * (-1) : 
textBox3.Text == "Long" ?
// do something on Convert.ToDouble(textBox2.Text) :
Convert.ToDouble(textBox2.Text);

CodePudding user response：

You can negate the position. This way you only need 1 operation.

if (textBox3.Text == "Long" || textBox3.Text == "Short") { positions = positions * -1; }

Ideally you want to do this in a method and pass a string parameter.
