我怎麼可以在C執行此＃有人可以幫助我

Question

在C＃

if txtbxquantity.text <=5  
then  
    txtbxhighlowitem.text = low item  
else  
    txtbxhighlowitem.text = high item  
end if  

Answer 1

也許你下一步想做我怎樣才能執行此：

int lowitem=0; 
int highitem=0; 
if(Convert.ToInt32(txtbxquantity.Text)<=5) 
    lowitem = Covnert.ToInt32(txtbxhighlowitem.Text); 
else 
    highitem = Covnert.ToInt32(txtbxhighlowitem.Text); 

或

private void button1_Click(object sender, EventArgs e) 
    { 
     string lowitem = "low item"; 
     string highitem = "high item"; 
     if (Convert.ToInt32(txtbxquantity.Text) <= 5) 
      txtbxhighlowitem.Text = lowitem; 
     else 
      txtbxhighlowitem.Text = highitem; 
    } 

Answer 2

if (txtbxquantity.Text <= "5") 
 
     { 
 
      txtbxhighlowitem.Text = "low item"; 
 
     } 
 
     else 
 
     { 
 
      txtbxhighlowitem.Text = "high item"; 
 
     }
