Visual Studio 2012 中的 ViewState 语法错误？

Question

I get a strange error message when using viewState on a web page. Using example code from Microsoft generates this error on ViewState["Text"]:

Error 17 Cannot apply indexing with [] to an expression of type 'method group'

It seems the error is not in the code, but in config or something.

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.IO;
using OfficeOpenXml;
using vaCommonLibrary;

public partial class lista : System.Web.UI.Page
{

    public String Text
    {
        get 
        { 
            object o = ViewState["Text"]; 
            return (o == null)? String.Empty : (string)o;
        }

        set
        {
            ViewState["Text"] = value;
        }
    }

I get another error further down in my code:

ViewState["SortDirection"] = sortDirection;

gives

Error 1 Invalid token '[' in class, struct, or interface member declaration

Problem solved.

Your second error sounds like that code isn't in the right place

Absolutely correct. The code was right, but further down in my code there was a { missing after an IF-statement, which caused later parentheses to mismatch leading to "strange" errors. I should have seen that, but I'm kind of new to C#, and just started to migrate all my VB.NET code to C#.

Thanks.
