一、软件介绍
今天给大家分享我自己编写的数据库表结构文档生成工具，方便大家在实际开发当中，可以很方便导出业务系统的表结构，也可以作为项目验收文档中数据库设计文档使用。这样可以大大减少编写数据库表结构文档的时间，有需要的朋友欢迎下载或者沟通交流！
二、技术框架
● 编程语言：C# （ Net Framework4.5.5）
● 数据库技术框架：Dapper
● 导出Word文档：NPOI
● 访问方式：WinForm窗体应用程序，Windows操作系统可以直接运行
三、功能介绍
● 支持SQLServer、MySQL（5.7、8.0）、SQLite 三种类型的数据，持续更新
● 支持Word、Html、MarkDown 三种格式的导出
● 导出内容包含数据表（字段详情、字段注释、长度、默认值等）、创建表脚本、视图及视图脚本、存储过程及脚本
● 支持生成文档的同时直接打开文档
● 支持数据库备份（目前只支持SQLServer导出bak备份文件）
四、代码展示
1、获取数据库信息部分代码
/// <summary>
/// 获取数据库字符串
/// </summary>
/// <param name="servername"></param>
/// <param name="uid"></param>
/// <param name="pwd"></param>
/// <param name="db"></param>
/// <returns></returns>

try
{
using (SqlConnection connection = new SqlConnection(conStr))
{
var list = connection.Query<string>(sql).ToList();
return list;
}
}
catch
{
return null;
}
}

try
{
using (SqlConnection connection = new SqlConnection(conStr))
{

}
}
catch
{
}
return list;
}
/// <summary>
/// 获取特定数据库里面的存储过程
/// </summary>
/// <param name="conStr"></param>

string sql = @" select name as viewName, (select text from syscomments where id=OBJECT_ID(name)) as viewDerails

}
/// <summary>

2、导出Html文档代码
/// <summary>
/// 生成html文件
/// </summary>
/// <param name="list"></param>
/// <param name="conStr"></param>
/// <param name="db"></param>
/// <param name="type"></param>
public void CreateToHtml(List<TableModel> list, string conStr, string db, int type, List<string> checkList)
{
StringBuilder sb = new StringBuilder();
sb.Append("<html><meta charset=\"utf-8\" /><meta http-equiv = \"Content-Language\" content = \"zh-CN\" >");
sb.Append("<head><title>数据库说明文档</title><body>");
sb.Append("<style type=\"text/css\">\n");
sb.Append("body { font-size: 9pt;}\n");
sb.Append(".styledb { font-size: 14px; }\n");
sb.Append(".styletab {font-size: 14px;padding-top: 15px; }\n</style></head><body>");
sb.Append("<h1 style=\"text-align:center;\">" + db + "数据库说明文档</h1>");
GetDBService(type);
#region 创建一个表格
if (checkList.Where(m => m.Equals("表")).Count() > 0)
{
sb.Append("<h2>一、表结构</h2>");
sb.Append("");
sb.Append("");
if (list.Count > 0)
{
foreach (var item in list)
{
if (item.tableDesc != null && item.tableDesc != "")
{
sb.Append("<h3>表名:" + item.tableName + "(" + item.tableDesc + ")</h3>");
}
else

}
sb.Append(" <table cellspacing=\"0\" cellpadding=\"5\" border=\"1\" width=\"100%\" bordercolorlight=\"#4F7FC9\" bordercolordark=\"#D3D8E0\">");
sb.Append("<thead bgcolor=\"#E3EFFF\"> <th>序号</th><th>字段名称</th><th>标识</th><th>主键</th><th>字段类型</th><th>字段长度</th><th>允许空值</th><th>字段默认值</th><th>字段备注</th></thead>");
sb.Append("<tbody>");
//从第二行开始 因为第一行是表头
int i = 1;
var tabledetaillist = service.GetTableDetail(item.tableName, conStr, db);
if (tabledetaillist != null && tabledetaillist.Count > 0)
{
foreach (var itm in tabledetaillist)

sb.Append("<h4>" + item.tableName + "建表脚本</h4><br/>");
sb.Append("<span>" + service.GetTableSQL(item.tableName, conStr) + "</span>");
}
}
}
#endregion
#region 存储过程
if (checkList.Where(m => m.Equals("存储过程")).Count() > 0)
{
List<ProcModel> proclist = new List<ProcModel>();
proclist = service.GetProcList(conStr, db);
sb.Append("<h2>二、存储过程</h2>");
if (proclist != null && proclist.Count > 0)

sb.Append("<span>" + item.proDerails + "</span>");
}
}
}
#endregion
#region 视图
if (checkList.Where(m => m.Equals("视图")).Count() > 0)

viewlist = service.GetViewList(conStr, db);
sb.Append("<h2>三、视图</h2>");

sb.Append("<span>" + item.viewDerails + "</span>");
}
}
}
#endregion
sb.Append("</body></html>");
sb.ToString();
string filename = db + "-数据库说明文档";//文件名
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.DefaultExt = "html";
saveDialog.Filter = "html文件|*.html";
saveDialog.FileName = filename;
saveDialog.ShowDialog();
filename = saveDialog.FileName;
if (filename.IndexOf(":") < 0) return; //被点了取消
StreamWriter sw1 = new StreamWriter(saveDialog.FileName, false);
sw1.WriteLine(sb);
sw1.Close();
System.Diagnostics.Process.Start(filename);
}
五、运行效果
应用程序主界面
支持三种生成文档类型：每次只能选择一种，推荐使用markdown格式
Word文档生成效果
Html文档生成效果
MarkDown文档效果
针对SQLServer数据库备份
