c# - 初始化字符串的格式不符合从索引 0 开始的规范

Question

我正在使用 Microsoft Enterprise Lip 我有这种方法可以在网站中插入资源 我得到了这个错误我不认为这是权限问题而且我真的不知道如何解决它。通过我测试 connectionStrings 的方式它工作正常

  <connectionStrings>
    <add name="SiteSqlServer"
      connectionString="Data Source=.;Initial Catalog=databaseName;User ID=sa;Password=***"/>
  </connectionStrings>

 public static int Insert(Resoursce r)
        {
            Database objDB = new SqlDatabase("SiteSqlServer");
            int val = 0;
            using (DbCommand cmd = objDB.GetStoredProcCommand("InsertResoursce"))
            {
                //  OutParameter
                objDB.AddOutParameter(cmd,"@OutResoursceID",DbType.Int32,int.MaxValue);

                //  iNParameter
                objDB.AddInParameter(cmd, "@ModuleId", DbType.Int32, r.ModuleId);
                objDB.AddInParameter(cmd, "@Summary", DbType.StringFixedLength, r.Summary);
                objDB.AddInParameter(cmd, "@PageId", DbType.StringFixedLength, r.PageID);
                objDB.AddInParameter(cmd, "@TypeId", DbType.Int32, r.TypeID);
                objDB.AddInParameter(cmd, "@UserID", DbType.Guid, r.UserID);
                objDB.AddInParameter(cmd, "@Enabled", DbType.Boolean, r.Enabled);
                objDB.AddInParameter(cmd, "@SafetyAlert", DbType.Boolean, r.SafetyAlert);
                objDB.AddInParameter(cmd, "@SaftyAlertText", DbType.StringFixedLength, r.SafetyAlertText);


                try
                {
                     val = objDB.ExecuteNonQuery(cmd);
                     if (val == 1)
                     {
                         return Convert.ToInt32(objDB.GetParameterValue(cmd, "@OutResoursceID"));
                     }
                     else
                     {
                         return -1;
                     }
                }
                catch (Exception ex)
                {


                    throw ex;
                } 

            }

这通常意味着您的连接字符串不好。如果您查看堆栈跟踪，您会注意到在尝试解释您的连接字符串时失败了。

检查您的连接字符串以确保它是正确的 - 或者将其张贴在这里寻求帮助(但不要包含任何敏感信息，例如密码 ;))

更新

根据SqlDatabase documentation SqlDatabase 类采用连接字符串，而不是连接字符串配置的键。

所以

new SqlDatabase("SiteSqlServer");

应该是

var connection = ConfigurationManager.ConnectionStrings["SiteSqlServer"];

Database objDB = new SqlDatabase(connection.ConnectionString);

(为简洁起见，我在这里省略了任何防御代码)
