Question

这是我的代码：

            SqlParameter rolename = new SqlParameter("rolename", SqlDbType.VarChar);
            rolename.Direction = ParameterDirection.Input;
            rolename.Value = "role";                

            SqlParameter password = new SqlParameter("password", SqlDbType.VarChar);
            password.Direction = ParameterDirection.Input;
            password.Value = "123@123";

            SqlParameter fCreateCookie = new SqlParameter("fCreateCookie", SqlDbType.Bit);
            fCreateCookie.Direction = ParameterDirection.Input;
            fCreateCookie.Size = 100;
            fCreateCookie.Value = true;                

            SqlParameter cookie = new SqlParameter("cookie", SqlDbType.VarBinary);
            cookie.Direction = ParameterDirection.Output;
            cookie.Size = 8000;

            _context.Database.ExecuteSqlCommand(TransactionalBehavior.DoNotEnsureTransaction, "EXEC sp_setapprole @rolename,@password,@fCreateCookie, @cookie OUT;", rolename, password, fCreateCookie, cookie);

我得到一个错误：

形式参数＆＃34; @ fCreateCookie＆＃34;未被声明为OUTPUT参数，但是在请求的输出中传递了实际参数。

有人能告诉我我做错了吗？

您缺少参数

    ALTER procedure [sys].[sp_setapprole]
        @rolename   sysname,        -- name app role
        @password   sysname,        -- password for app role
-->     @encrypt    varchar(10) = 'none',       -- Encryption style ('none' | 'odbc')
        @fCreateCookie bit = 0,  
        @cookie varbinary(8000) = 0xFFFFFFFF OUTPUT
    as

你需要添加一个参数者@encrypt =＆＃39; none＆＃39;在executeccommand调用

之前的@fcreatecookie之前

从ExecuteSqlCommand执行Sp_SetAppRole
