首先,准备工作:
-
创建一个Access 数据库,命名AccessTest.accdb,添加一些数据用于测试
准备System.Data.dll与System.EnterpriseServices.dll两个插件,这是访问Access数据需要引用的dll
如果完成后需要在其他电脑*问,并且该电脑没有安装Office,就可以要求他安装access访问组件,然后就可以运行了,所有的相应组件与代码,后面都会给一个网盘链接
然后开始创建Unity工程
1.在unity工程文件夹Assets同级目录下创建一个SQLData文件夹用来存放Access数据库文件AccessTest.accdb
2.在unity工程文件夹Assets目录下创建一个Plugins文件夹用来存放System.Data.dll与System.EnterpriseServices.dll两个dll文件
3.创建一个功能脚本AccessData.cs,用来访问Access数据库
using System.Data.Odbc;
using System.Data;
using System;
/****************************************
* 功能:访问access数据库.
* 创建: 2015-10-19 _D
*
* *************************************/
public class AccessData
{
/// <summary>
/// 本类对象
/// </summary>
private static AccessData accessData;
/// <summary>
/// 连接对象
/// </summary>
private OdbcConnection con; /// <summary>
///初始化并返回本类对象
/// </summary>
/// <returns></returns>
public static AccessData getInstance()
{
if (accessData == null)
{
accessData = new AccessData();
accessData.con = new OdbcConnection();
}
return accessData;
} /// <summary>
/// 数据库连接函数
/// </summary>
/// <param name="accessPath">access数据库路径</param>
public void Connection(string accessPath)
{
string connection = "Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=" + accessPath;
con.ConnectionString = connection;
try
{
if(con.State==ConnectionState.Closed)
con.Open();
}
catch (Exception e)
{
throw new Exception(e.Message);
}
} /// <summary>
/// 断开与数据库的连接
/// </summary>
public void Colse()
{
if (con.State != ConnectionState.Closed)
{
con.Close();
}
}
/// <summary>
/// 操作数据库
/// </summary>
/// <param name="sql">sql语句</param>
/// <param name="dataTableName">返回的DataTable的名称</param>
/// <returns></returns>
public DataTable OperateAccess(string sql, string dataTableName)
{
OdbcCommand cmd = new OdbcCommand(sql,con);
DataTable dt = new DataTable(dataTableName);
OdbcDataReader reader = cmd.ExecuteReader();
dt.Load(reader);
reader.Close();
return dt;
}
}
4.创建一个测试脚本Test.cs,用来具体操作Access数据库
using UnityEngine;
using System.Collections;
using System.Data; public class Test : MonoBehaviour {
/// <summary>
/// Access数据库路径
/// </summary>
private string accessPath; // Use this for initialization
void Start () {
accessPath = Application.dataPath;
int num=accessPath.LastIndexOf("/");
accessPath = accessPath.Substring(0, num);
accessPath += "/SQLData/AccessTest.accdb"; AccessData.getInstance().Connection(accessPath);
} string text = "";
// Update is called once per frame
void OnGUI () {
if (GUI.Button(new Rect(0, 0, 100, 30), "查询"))
{
string sql = "select * from t_First";
DataTable dt = AccessData.getInstance().OperateAccess(sql, "select_t_First"); for (int i = 0; i < dt.Rows.Count; i++)
{
for (int j = 0; j < dt.Columns.Count; j++)
{
text +=dt.Columns[j].ColumnName + ":" + dt.Rows[i][dt.Columns[j].ColumnName]+" ";
}
text += "\n";
}
}
GUI.Label(new Rect(0, 60, 200, 60), text);
}
}
5.将Test脚本绑定在场景物体中,运行测试
