    class Program
    {
        static void Main(string[] args)
        {
            string connsql = "Data Source=" + Environment.MachineName + ";Integrated Security=True;Pooling=False;MultipleActiveResultSets=False;Packet Size=4096";
            SqlConnection conn = new SqlConnection(connsql);
            conn.Open();
            StreamReader readfilequery = new StreamReader(@"J:\Project\Finelf\Dental lab and Storeff\Main Form\query\script.sql");
            string query = readfilequery.ReadToEnd();
            SqlCommand commqnd = new SqlCommand(query, conn);
            commqnd.ExecuteNonQuery();//(here throw Exception)
        }
    }
}

推荐答案

您必须逐个拆分查询并执行命令。这并不难。基本上，您累积行直到找到带有GO的行，然后执行该查询。然后跳过该行（使用GO）并开始累积下一个查询。然后重复，直到你到达文件末尾。

You will have to split the query and execute command one by one. It is not that hard. Essentially, you accumulate lines until you find a line with "GO" and then you execute that query. You then skip that line (with "GO") and start accumulating next query. You then repeat until you reach then end of the file.

非常感谢

看我写这个代码它成功了

这是解决方案

thank you very much
look i wrote this code it is succeeded
this is solution

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using System.IO;
namespace ConsoleApplication11
{
    class Program
    {
        static void Main(string[] args)
        {
            string connsql = "Data Source=" + Environment.MachineName + ";Integrated Security=True;Pooling=False;MultipleActiveResultSets=False;Packet Size=4096";
            SqlConnection conn = new SqlConnection(connsql);
            conn.Open();
            StreamReader readfilequery = new StreamReader(@"J:\Project\Finelf\Dental lab and Storeff\Main Form\query\script.sql");
            string query = "";
            string line = readfilequery.ReadLine();
            while (line != null)
            {
                if (line.IndexOf("GO") == -1)
                {
                    query =query +" "+ line;
                }
                else
                {
                    SqlCommand commqnd = new SqlCommand(query, conn);
                    commqnd.ExecuteNonQuery();
                    query = null;
                }
                line = readfilequery.ReadLine();
            }
            
        }
    }
}

Noze的代码不会运行最后一个块命令..

小修复：

Noze's code would not run the last block of commands..
small fix:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using System.IO;
namespace ConsoleApplication11
{
    class Program
    {
        static void Main(string[] args)
        {
            string connsql = "Data Source=" + Environment.MachineName + ";Integrated Security=True;Pooling=False;MultipleActiveResultSets=False;Packet Size=4096";
            SqlConnection conn = new SqlConnection(connsql);
            conn.Open();
            StreamReader readfilequery = new StreamReader(@"J:\Project\Finelf\Dental lab and Storeff\Main Form\query\script.sql");
            string query = "";
            string line = readfilequery.ReadLine();
            while (line != null)
            {
                if (line != "GO")
                {
                    query =query +" "+ line;
                }
                else
                {
                    (new SqlCommand(query, conn)).ExecuteNonQuery();
                    query = null;
                }
                line = readfilequery.ReadLine();
            }
            if (!string.IsNullOrEmpty(query)) //last time
            {
                (new SqlCommand(query, conn)).ExecuteNonQuery();
                query = null;
            }
        }
    }
}
