推荐答案
检查此
Hi ,
Check this
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string val = "مشرف لوحة أجهزة القياس";
trans.InnerHtml = TranslateText(val, "ar|en");
}
}
public string TranslateText(string input, string languagePair)
{
string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
WebClient webClient = new WebClient();
webClient.Encoding = System.Text.Encoding.UTF8;
string result = webClient.DownloadString(url);
int len = result.Length;
result = result.Remove(0, result.IndexOf("id=result_box"));
int len2 = result.Length;
result = result.Remove(result.IndexOf("</span>"));
return "<span"+ result +"</span>";
}
<body>
<form id="form1" runat="server">
<div id="trans" runat="server">
</div>
</form>
</body>

您应该检查res1和res2的值是否不超过结果的长度(因为它是第一次分配的.您可能只想放子字符串中的其他值，而不是重复使用几次结果，以使其更清晰，更容易调试)
另外，如果IndexOf找不到您要查找的内容，它将得到-1，这也不是有效的索引.您可能还需要检查一下.
祝你好运！
You should check if the value of both res1 and res2 won''t exceed the length of result (as it is first assigned. you might simply want to put the substring in some other value instead of reusing result a few times to keep it more clear and easier to debug)
Also, if IndexOf can''t find what you are looking for it will give you -1, which isn''t a valid index either. You might also want to check that.
Good luck!
