Question

我有MVC5工作。我创建了本地数据库连接本地sql服务器后，我创建了门户网站其工作服务器数据库连接，而不是连接数据库。服务器数据库连接使用

Appseetings.config 

 <?xml version="1.0"?>
    <appSettings>

      <add key="webpages:Version" value="2.0.0.0" />
      <add key="webpages:Enabled" value="false" />
      <add key="PreserveLoginUrl" value="true" />
      <add key="ClientValidationEnabled" value="true" />
      <add key="UnobtrusiveJavaScriptEnabled" value="true" />

      <add key="DefaultMembershipName" value="UserName" />

      <add key="SmtpServer" value="relay-hosting.secureserver.net" />
      <add key="SmtpPort" value="25" />
      <add key="UserId" value="thenna41@gmail.com" />
      <add key="Password" value="pixel@1990" />


      <add key="DefaultTheme" value="Theme1"/>
      <add key="webpages:Version" value="3.0.0.0" />
      <add key="webpages:Enabled" value="false" />
      <add key="ClientValidationEnabled" value="true" />
      <add key="UnobtrusiveJavaScriptEnabled" value="true" />
         <!--<add key="thenna" value="server=121.11.1.2;database=montage;user id=montage;password=pass;trusted_connection=false;"/>-->

          <!--<add key="thenna" value="server=DESKTOP-QD6A981\SQLEXPRESS;user id=montage;password=montage;trusted_connection=false;" />-->

          <add key="thenna" value="server=DESKTOP-QD6A981\SQLEXPRESS;trusted_connection=true;" />

          <add key="CustomAuthentication.LoginUrl" value="/Account/LogOn" />
          <add key="CustomAuthentication.Cookie.Name" value=".CUSTOM_AUTH" />
          <add key="CustomAuthentication.Cookie.Expiration" value="1" />
          <add key="CustomAuthentication.Cookie.Timeout" value="20" />

        </appSettings>

我已将本地数据库配置称为无法正常工作

key="thenna" - ＆gt;用于从数据库连接中读取字符串

Appsettings Reader用于读取thenna键值

public class HomeSqlRepository : Repository
    {
        public string ConnectionString { get; set; } = AppSettingsReader.ReadString("thenna");
        const int MaxItemCount = 1000;
        public enum SqlExecuteType
        {
            Scalar, NonQuery, Reader
        }
        public async Task<string> ExecuteSqlAsync(string procname, SqlExecuteType executiontype, IDictionary<string, string> parameters)
        {
            string ret = "";

            using (SqlConnection sqlConn = new SqlConnection(ConnectionString))
            {
                using (SqlCommand sqlCmd = new SqlCommand(procname, sqlConn))
                {
                    sqlCmd.CommandType = CommandType.StoredProcedure;
                    foreach (KeyValuePair<string, string> kvp in parameters)
                    {
                        sqlCmd.Parameters.AddWithValue(kvp.Key, kvp.Value);
                    }
                    sqlConn.Open();
                    if (executiontype == SqlExecuteType.Scalar)
                        ret = (await sqlCmd.ExecuteScalarAsync()).ToString();
                    else if (executiontype == SqlExecuteType.NonQuery)
                        ret = (await sqlCmd.ExecuteNonQueryAsync()).ToString();
                    sqlConn.Close();
                }
            }

            return ret;
        }

        public T  GetItem<T>(string procname, IDictionary<string, object> parameters)
        {

            procname.ThrowIfNull();



            using (IDbConnection db = new SqlConnection(ConnectionString))
            {
              var result= db.Query<T>(sql: procname, param: BuildQueryParameter(parameters), commandType: CommandType.StoredProcedure);
                return result.FirstOrDefault();
            }


        }

应用程序设置使用cloudconfirmationmanager的阅读器使用以下代码

  public static class AppSettingsReader
    {
        public static string ReadString(string key)
        {
            try
            {
                return CloudConfigurationManager.GetSetting(key).ToString();
            }
            catch(System.Exception ex)
            {
                throw ex;
            }
        }

        public static int ReadInt(string key)
        {
            try
            {
                return int.Parse(CloudConfigurationManager.GetSetting(key).ToString());
            }
            catch (System.Exception ex)
            {
                throw ex;
            }
        }
}

在哪里读取值我创建了db本地但不起作用但是当连接服务器时它正在工作。这里有什么错误？提前谢谢

Answer 1

将您的连接字符串更改为

<add key="thenna" value="Data Source=DESKTOP-QD6A981\SQLEXPRESS;Integrated Security=True" />

如果这不起作用，请分享您遇到的错误。

本地数据库不工作
