Comparison of two textboxs

Question

Dear Friends,
I want to compare two values of textboxs please, check my code

Int32 val11 = Convert.ToInt32(textBox4.Text);
 Int32 val22 = Convert.ToInt32(textBox10.Text);
 if(val11 >> val22)
 { 
 MessageBox.Show("Please, check Maximum Limit of Quantity.Quantity should be less tha fix Limit", "Limit", MessageBoxButtons.AbortRetryIgnore, MessageBoxIcon.Warning);
                        textBox15.Focus();
                        textBox4.ForeColor = Color.Red;
 }

                        textBox4.ForeColor = Color.Green;
 }

I got error.

Error CS0029 Cannot implicitly convert type 'int' to 'bool'

This line is giving an error. if ( val11 >> val22 ) You are expected to have boolean value as return type for the condition expression whereas you are doing bitwise shift operation which returns integer. try doing if ( val11 > val22 )

Convert.ToInt32() may throw an exception, if the input string is not able to convert into number. Therefore, use Int32.TryParse() method to avoid exception. Int32 val11; Int32 val22; Int32.TryParse(textBox4.Text, out val11); Int32.TryParse(textBox10.Text, out val22); if (val11 > val22) { MessageBox.Show( "Please, check Maximum Limit of Quantity.Quantity should be less tha fix Limit" , "Limit" , MessageBoxButtons.AbortRetryIgnore, MessageBoxIcon.Warning); textBox15.Focus(); textBox4.ForeColor = Color.Red; } else { textBox4.ForeColor = Color.Green; }
