嗯嗯.. 我有一个本地数据库 .. 使用 VS 2012 创建 .. 不是 LocalDB .. 它的 SqlExpress x64 ..

我有一个 C# 程序，它读取和解析一个 txt 文件.. 并将数据转换为记录.. 在一个执行流程中插入大约 200,000 条记录.. 程序解析并创建一个插入查询并执行它..

我使用了 Sql 对象 .. SqlCommand .. SqlConnection ..... 用于插入 ..

问题是控制台 C# 应用程序确实显示所有记录都已成功插入，直到最后计数..

但我只能在数据库表中看到 1000 条记录..

要插入的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using System.IO;

namespace SentiWordDBPopulate
{
class DBPopulateSentiWord
{
    static SqlCommand sqlCmd;
    static SqlConnection sqlConn;

    static void Main(string[] args)
    {
        try
        {
            sqlConn = new SqlConnection("server=localhost\\SqlExpress; DataBase=WordDBForBlogMiner; integrated security=true");
            sqlConn.Open();
            //sqlCmd = new SqlCommand("select * from KWTable", sqlConn);

            //skip 1st 13 lines
            //for (int i = 1; i <= 13; i++)
            //fin.ReadLine();

            string[] lines = File.ReadAllLines("C:\\Users\\Ritesh\\Desktop\\WordDB.txt");

            Console.WriteLine("Done reading! Press enter to insert everything into DB.");
            Console.Read();

            long IDCounter = 0;
            //enter next 117658 lines into DB
            for (int i = 13; i < lines.Length; i++)
            {
                //string line =fin.ReadLine();
                string[] s = (lines[i].Remove(lines[i].IndexOf('#')).Split(new char[] { '\t' }, StringSplitOptions.RemoveEmptyEntries));
                //s[5] = s[6] = null;
                s[2] = s[2].Equals("NaN") ? "0" : s[2];
                s[3] = s[3].Equals("NaN") ? "0" : s[3];
                float tempNegScore = float.Parse(s[3]), tempPosScore = float.Parse(s[2]);
                int negScore = (int)Math.Round((tempNegScore * 27), MidpointRounding.AwayFromZero);
                int posScore = (int)Math.Round((tempPosScore * 31), MidpointRounding.AwayFromZero);

                if (posScore <= 31 && negScore <= 27)
                {
                    //Console.WriteLine((++IDCounter) + "\t => " + s[0] + "\t" + posScore + "\t" + negScore + "\t" + s[4]);
                    string category = "";
                    if (posScore.Equals(0) && negScore.Equals(0))
                        category = "neutral";
                    else if (posScore > 0 && negScore.Equals(0))
                        category = "positive";
                    else if (posScore.Equals(0) && negScore > 0)
                        category = "negative";
                    else if (posScore > 0 && negScore > 0)
                        category = "PosNeg";

                    string query = "insert into SentiWordKWTable values ('" + s[0] + "', " + (++IDCounter) + ", " + posScore + ", " + negScore + ", '" + s[4].Replace("'", "") + "', '" + category + "')";
                    sqlCmd = new SqlCommand(query, sqlConn);
                    sqlCmd.ExecuteNonQuery();
                    Console.WriteLine("Record Num: " + IDCounter + " successfully inserted!");
                }
                else
                {
                    Console.WriteLine((++IDCounter) + "\t => " + s[0] + "\t" + posScore + "\t" + negScore + "\t" + s[4]);
                    break;
                }

                tempNegScore = tempPosScore = 0;
                posScore = negScore = 0;
            }
            Console.Read();
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception occured => " + e.Message);
            sqlCmd = new SqlCommand("delete from SentiWordKWTable", sqlConn);
            sqlCmd.ExecuteNonQuery();
            Console.WriteLine("all rows of table deleted");
        }
        Console.Read();
    }
}

}

在 VS 2008 早期这不是问题 .. VS 2012 中是否有一些限制 .. 或者可以启用 >1000 插入的东西？..

它只是可见性选项。顶部有一个小工具栏，其中有一个字段： Max Rows: 1000 我在其中选择了“全部”，一切都是可见的...... * facepalm *

很抱歉给大家带来麻烦，感谢@MarcGravell，我将使用参数而不是串联。
