我已经遍寻搜索,但无法弄清楚这里有什么问题。我有一个webb c#应用程序。我有一个c#方法在我查询数据库的应用程序文件夹中,然后想要将该值传递回我的Cshtml页面,在那里我将根据值进行makin deciaions。不纠结我做什么,当我打电话的方法,然后尝试读取我的错误“无法键入‘1类’隐式转换为字符串值。从CSHTML文件中调用另一个类的方法
这里是我的C#类的方法和下面的电话
方法:
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public class class1
{
public static string getdata()
{
string cnnString = ConfigurationManager.ConnectionStrings["GDC_WellsFargoConnectionString"].ConnectionString;
SqlDataReader reader;
string returnValue;
/// var cmd = "insert into Email Insert values(@name,@email";
string userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
using (SqlConnection cnn = new SqlConnection(cnnString))
{
using (SqlCommand cmd = new SqlCommand("Select isnull([Authorization],'none') as authoriztion from PNSWebAuthorization where username = '" + userName + "'", cnn))
{
////cmd.Parameters.AddWithValue("@name", "Newname,First");
//// cmd.Parameters.AddWithValue("@email", "[email protected]");
///string authcode;
cnn.Open();
try {
reader = cmd.ExecuteReader();
if (reader.Read())
{
returnValue = reader["Authorization"].ToString();
reader.Close();
return returnValue;
}
else
{
reader.Close();
return "";
}
}
catch (Exception err)
{
throw new ApplicationException(err.Message);
}
finally
{
cnn.Close();
cnn.Dispose();
}
}
}
}
CSHTML Calling
@model GDC.Finance.WebClient.Areas.Treasury.ViewModels.CashReceiptSessionListViewModel
@using PagedList.Mvc;
@{
ViewBag.Title = "Cash Receipt Sessions test";
}
<h2>Sessions</h2>
@section scripts{
<script src="~/Scripts/popup.js"></script>
}
@{
/// string auth = "none";
var auth = new class1();
class1.getdata();
string rights = auth;
}
Auth throws the error.
