Question

我有以下SP来电

        public IEnumerable<classfile> GetData(bool isactive)
        {
            using (SqlConnection cnn = this.OpenConnection())
            {

                 IList<classfile> SampleList = SqlMapper.Query<classfile>(cnn, "SPName").ToList();

                cnn.Close();

                return SampleList.ToList();
            }
        }

如何发送参数以及上面的dapper SP调用

我试过了

        public IEnumerable<classfile> GetData(bool isactive)
        {
            using (SqlConnection cnn = this.OpenConnection())
            {
                 var parameters = new DynamicParameters();
                 parameters.Add("@isActive", isactive);

                 IList<classfile> SampleList = SqlMapper.Query<classfile>(cnn, "SPName", parameters).ToList();

                cnn.Close();

                return SampleList.ToList();
            }
        }

但是其运行时间会出现以下错误

程序或功能＆＃39; SPName＆＃39;期望参数＆＃39; @ isActive＆＃39;，哪个没有提供。

Answer 1

自己找到答案

    public IEnumerable<classfile> GetData(bool isactive)
    {
        using (SqlConnection cnn = this.OpenConnection())
        {
             DynamicParameters parameters = new DynamicParameters();
             parameters.Add("@isActive", isactive);

             IList<classfile> SampleList = SqlMapper.Query<classfile>(cnn, "SPName", parameters, commandType: CommandType.StoredProcedure).ToList();

            cnn.Close();

            return SampleList.ToList();
        }
    }

Answer 2

或者你可以写这样的东西

            IList<classfile> SampleList = SqlMapper.Query<classfile>(cnn, "SPName", new
            {
                isActive = isactive
            }
            , commandType: CommandType.StoredProcedure).ToList();

通过C＃中的SqlMapper.Query调用存储过程时发送参数
