如何在具有GUID主键和默认newsequentialid()的表上使用SQLBulkCopy？

CREATE TABLE #TempTable
(
    Column1 int,
    Column2 varchar(50),
    ...
)

INSERT INTO #TempTable (Column1, Column2, ...)
VALUES (Value1, Value2, ...)

using System.Data.SqlClient;
using System.Data;
using System.IO;

// 连接到数据库
using (SqlConnection connection = new SqlConnection("ConnectionString"))
{
    connection.Open();

    // 创建一个事务
    using (SqlTransaction transaction = connection.BeginTransaction())
    {
        try
        {
            // 创建一个SQLBulkCopy对象
            using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(connection, SqlBulkCopyOptions.Default, transaction))
            {
                // 设置目标表名
                sqlBulkCopy.DestinationTableName = "TargetTable";

                // 设置列映射
                sqlBulkCopy.ColumnMappings.Add("Column1", "Column1");
                sqlBulkCopy.ColumnMappings.Add("Column2", "Column2");
                ...

                // 执行批量复制操作
                sqlBulkCopy.WriteToServer(reader);
            }

            // 提交事务
            transaction.Commit();
        }
        catch (Exception ex)
        {
            // 回滚事务
            transaction.Rollback();
        }
    }
}

DROP TABLE #TempTable
