c# - 强制参数，Dapper 和 System.Data.SqlClient.SqlException

Question

我正在使用 Dapper 调用具有强制参数 @idProject 的存储过程

这是我的代码片段:

using (var c = _connectionWrapper.DbConnection)
      {
        var result = c.Query<Xxx>("dbo.xxx_xxxGetPage", new { @idProject = 1 }).AsList();
        return result;
      }

应该工作但引发异常:

An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll but was not handled in user code

Additional information: Procedure or function 'xxxGetPage' expects parameter '@idProject', which was not supplied.

为什么？

Answer 1

我认为您缺少 CommandType。

using (var c = _connectionWrapper.DbConnection)
{
    var result = c.Query<Xxx>("dbo.xxx_xxxGetPage", new { idProject = 1 }, commandType: CommandType.StoredProcedure).AsList();
    return result;
}

默认情况下，dapper 使用文本。
