string sqlcode = NewCompileCode.TransformSqlCode(queryCode);

把NewCompileCode.TransformSqlCode(queryCode);这个方法贴出来看看

[暖枫无敌]

string sqlcode = NewCompileCode.TransformSqlCode(queryCode);
中方法的代码有问题。

[mengxiaoqi]

public static string TransformSqlCode(string code)
{
code = Gueiwei(code);
char[] chars = code.ToCharArray();
StringBuilder sb = new StringBuilder();

for (int i = 0; i < chars.Length; i++)
{
for (int j = 0; j < IntTable.Length; j++)
{
if (chars[i] == table[IntTable[j]])
{
sb.Append(table[j]);
break;
}
}
}


return sb.ToString();
}
/// 将数据库防伪码转换成查询形式

public static string SqlCodeTransformCode(string sqlCode)
{
char[] chars = sqlCode.ToCharArray();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < chars.Length; i++)
{
for (int index = 0; index < table.Length; index++)
{
if (chars[i] == table[index])
{
sb.Append(table[IntTable[index]]);
}
}
}
return huanwei(sb.ToString());
}谢谢了要帮帮我啊

[格桑花]

你检查一下是不是数组中的值为空，

[mengxiaoqi]

.....怎么检查啊?....我刚学好多都不懂

像这种问题太好解决了，.net有那么好的调试工具干嘛不用，就是索引出界了啊，就是数组实际长度没有你要取的索引罢了，要么就是过长，要么就是过短，楼主你自己试着调试进去看看不就知道了

[mengxiaoqi]

姐姐 我我不会调啊

[chongchonglovenet]

の…………真没办法，
哈哈
步骤一：在你要断点的地方按F9，然后设置要首次加载的页面，设为启动项目；
步骤二：在按F5，就可以调试了，哈哈…
哥哥写得清楚了吗？

[mengxiaoqi]

谢谢谢谢~
