我在SQL Server中有一个存储过程,该存储过程接受用户定义的表类型。我正在关注这篇帖子的答案从C#列表批量插入SQL Server到具有外键约束的多个表中有关如何将DataTable发送到SQL中的存储过程。
I have a stored procedure in SQL Server that accepts a User-Defined Table Type. I'm following the answer from this post Bulk insert from C# list into SQL Server into multiple tables with foreign key constaints on how to send a DataTable to a stored procedure in SQL.
但是当我创建 DataTable table = new DataTable(); 时出现错误,提示 DataTable不包含一个接受0个参数的构造函数。
But when I create DataTable table = new DataTable(); I get an error that DataTable does not contain a constructor that takes 0 arguments.
我发现了这个 github/VahidN/EPPlus.Core/issues/4 基本上说 DataTable 是.NET Core不再支持。那么现在怎么办?如何创建数据表(或其替代品)?如何将用户定义的表类型发送到.NET Core上的SQL Server?
I found this github/VahidN/EPPlus.Core/issues/4 which basically saying DataTable is no longer supported in .NET Core. So now what? how do I create a DataTable (or what is it's replacement)? how do I send a User-Defined Table Type to SQL Server on .NET Core?
推荐答案.NET现在支持DataTable核心2.0。在 .Net Core如何实现SQLAdapter ./ DataTable中查看我的答案功能。下面的示例代码在2.0中可用。
DataTable is now supported in .NET CORE 2.0. See my answer at .Net Core how to implement SQLAdapter ./ DataTable function . Sample code below works in 2.0.
public static DataTable ExecuteDataTableSqlDA(SqlConnection conn, CommandType cmdType, string cmdText, SqlParameter[] cmdParms) { System.Data.DataTable dt = new DataTable(); System.Data.SqlClient.SqlDataAdapter da = new SqlDataAdapter(cmdText, conn); da.Fill(dt); return dt; }更多推荐
在.NET Core中使用DataTable
