小巧的人怎么了？

Question

我有这段代码应该可以正常工作，但这会引发异常必须声明变量标量

 public async Task<Job> GetJobByUd(Guid jobId)
    {
        var sql = "select * from dbo.Jobs where JobId = @jobId;";
        using (DbConnection db = new SqlConnection(_connectionString))
        {
            var job = await db.QuerySingleOrDefaultAsync<Job>(sql, new {jobId});
            return job;
        }

    }

Answer 1

尝试这样，应该可以。

public async Task<Job> GetJobByUd(Guid jobId)
    {
        var sql = "select * from dbo.Jobs where JobId = @jobId;";
        using (DbConnection db = new SqlConnection(_connectionString))
        {
            var job = await db.QueryAsync<Job>(sql, new {jobId = jobId}).FirstOrDefault();
            return job;
        }

    }
