这篇博客介绍了如何使用C#来同步SQL Server数据库的Schema。内容包括编写SQL处理类、数据库类型类，以及执行数据库Schema同步的函数。虽然示例简单，但可以作为进一步扩展，处理约束、双主键和外键等复杂情况的基础。

C#同步SQL Server数据库Schema

1. 先写个sql处理类：

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

namespace PinkDatabaseSync
{
    class DBUtility : IDisposable
    {
        private string Server;
        private string Database;
        private string Uid;
        private string Password;
        private string connectionStr;
        private SqlConnection sqlConn;

        public void EnsureConnectionIsOpen()
        {
            if (sqlConn == null)
            {
                sqlConn = new SqlConnection(this.connectionStr);
                sqlConn.Open();
            }
            else if (sqlConn.State == ConnectionState.Closed)
            {
                sqlConn.Open();
            }
        }

        public DBUtility(string server, string database, string uid, string password)
        {
            this.Server = server;
            this.Database = database;
            this.Uid = uid;
            this.Password = password;
            this.connectionStr = "Server=" + this.Server + ";Database=" + this.Database + ";User Id=" + this.Uid + ";Password=" + this.Password;
        }

        public int ExecuteNonQueryForMultipleScripts(string sqlStr)
        {
            EnsureConnectionIsOpen();
            SqlCommand cmd = sqlConn.CreateCommand();
            cmd.CommandType = CommandType.Text;
            cmd.CommandText = sqlStr;
            return cmd.ExecuteNonQuery();
        }
        public int ExecuteNonQuery(string sqlStr)
        {
            EnsureConnectionIsOpen();
