} 此段代码网络上出现在很多不同的地方，已经搞不清是出自哪位高人之手了，所以在感激的同时感到抱歉无法注明出处了，希望更多的人能够从中受益。 另一段C#代码：using UnityEngine;
using System;
using System.Collections;
using System.Data;
public class DataBaseTest : MonoBehaviour {
public GUISkin myGUISkin = new GUISkin();
string strID = "";
string strName = "";
string strSex = "";
int Index = 1;
// Use this for initialization
void Start () {
}
void OnGUI()
{
GUI.skin = myGUISkin;
if (GUI.Button(new Rect(100,320,100,100),"Click Me"))
{
foreach(DataRow dr in CMySql.MyObj.Tables[0].Rows)
{
if (Index.ToString() == dr["ID"].ToString())
{
strID = dr["ID"].ToString();
strName = dr["Name"].ToString();
strSex = dr["Sex"].ToString();

break;
}
}
Index++;
if(Index > 5)
{
Index = 1;
}

}
GUI.Label(new Rect(320,100,150,70),"DataBaseTest");
GUI.Label(new Rect(300,210,150,70),strID);
