如果錯誤處理ASP.net web窗體

Question

如何顯示消息並停止運行剩餘的代碼。

例如。

if (num == -1){ 

    message.Text = "wrong"; 

} 

int happy == 0; 

if (happy != 0) 
{ 

    message.Text = "wrong"; 

} 

如果num = -1，它應該顯示消息並且不執行剩餘的代碼。

我該怎麼做？

p.s.這只是一個例子

Answer 1

只是把return那裏，代碼將停止。

if (num == -1){ 

message.Text = "wrong"; 
return; 
} 

int happy == 0; 

if (happy != 0) { 

message.Text = "wrong"; 
return; 
} 

Answer 2

選項1：

message.Text = string.Empty; 
int happy == 0; 
if (num == -1){ 
    message.Text = "wrong"; 
} 
else if (happy != 0) { 
    message.Text = "wrong"; 
} 

if(message.Text == "") 
{ 
// Remaining code 
} 

選項2：

if (num == -1){ 
    message.Text = "wrong"; 
    return; 
} 
if (happy != 0) { 
    message.Text = "wrong"; 
    return; 
} 
// Remaining code below this will only execute if num != -1 or happy == 0
