运算符"+"不能应用于类型为字符串"和方法组"的操作数

hi all,

i got the given error, please let me know if anybody knows this..


Operator ''+'' cannot be applied to operands of type ''string'' and ''method group''

Source Error:

Line 190:
Line 191:                strsubject = Session["user_name"] + " - Updated Account";
Line 192:                strbody = " Hi " + Session["user_name"] + ",<br>" + "      You have successfully Allocated new Destination details. Please find the details below:<br><br> " + "       Access Number      - '" + accessnumber + "' <br>" + "       Destination Number  - '" + TextBoxDest.Text.Trim + "'     <br>" + "       Reference Name     - '" + TextBoxRef.Text.Trim + "'     <br><br>";
Line 193:                strbody = strbody + " Thank you for choosing this.<br><br>.";
Line 194:                if (Session["user_email"] != null)

我的代码是:

my code is:

string strsubject = null;
                string strtoaddress = null;
                string strbody = null;
                string strcc = null;
                string strbcc = null;

                strsubject = Session["user_name"] + " - Updated Account ";
                strbody = " Hi " + Session["user_name"] + ",<br>" + "      You have successfully Allocated new Destination details. Please find the details below:<br><br> " + "       Access Number      - '" + accessnumber + "' <br>" + "       Destination Number  - '" + TextBoxDest.Text.Trim + "'     <br>" + "       Reference Name     - '" + TextBoxRef.Text.Trim + "'     <br><br>";
                strbody = strbody + " Thank you for choosing this .<br><br>.";
                if (Session["user_email"] != null)
                {
                    strtoaddress = Session["user_email"] + ConfigurationManager.AppSettings["SendMail_from"];
                }

推荐答案

由于您正在使用C#，因此它必须是

Since you are using C# it needs to be

TextBoxDest.Text.Trim()

请注意括号.

Note the parentheses.

TextBoxDest.Text.Trim应为TextBoxDest.Text.Trim()和
TextBoxRef.Text.Trim应该是TextBoxRef.Text.Trim()

TextBoxDest.Text.Trim should be TextBoxDest.Text.Trim() and
TextBoxRef.Text.Trim should be TextBoxRef.Text.Trim()

好吧，我现在无法访问ASP.NET服务器，所以这只是一个猜测，但是更改

Well, I can''t now access to an ASP.NET server, so it''s only a guess, but what about changing

TextBoxRef.Text.Trim

到

TextBoxRef.Text.Trim()

吗?很简单，我想您错过了方括号.

? Simple, I think you missed the brackets.
