运行 SPR 时，ExecuteReader 不支持获取 MultiExec

Question

我写了下面的方法

public async Task<DataTable> ExecuteProcedureToDataTableAsync(string spName, object parameters, int? commandTimeout = null, bool userPrefix = false)
    {
        using (var connection = new SqlConnection(_ConnectionString))
        {
            string spNameWithPrefix = GetSpNameWithPrefix(spName, userPrefix);
            var dt = new DataTable();
            _Logger.Debug($"Executing Query: [{spNameWithPrefix}], with params:[{parameters.ToJsonString()}]");
            dt.Load(await connection.ExecuteReaderAsync(spNameWithPrefix, parameters, commandTimeout: commandTimeout, commandType: CommandType.StoredProcedure));
            _Logger.Debug($"Completed Query To DataTable: [{spNameWithPrefix}], result columnCount:[{dt.Columns.Count}], result row count:[{dt.Rows.Count}]");
            return dt;
        }
    }

然后像这样调用它：

using (var results = await ExecuteProcedureToDataTableAsync(StoredProcedureFullName, StoredProcedureParams, Timeout, userPrefix: false))
{
    ExportReport(requestModel, results);
}

我得到了例外：

ExecuteReader 不支持 MultiExec

spr 不支持执行Reader 吗？

Answer 1

ExecuteReader 不支持多次执行。请改用QueryMultiple。
