我想使用调查的名称作为会议

如果您想与密钥调查名称创建一个会话，然后你做这个

 字符串surveyName = txtsurvey.Text;
会话[SurveyName] = surveyName; //或任何值，要在会话对象分配。

解决方案

i want to use Survey name as session

If you want to create a session with key as Survey Name then you do this

string surveyName = txtsurvey.Text;
Session["SurveyName"] = surveyName;  // or whatever value, you want to assign in session object.
