SqlConnection conn = new SqlConnection(strConn)这句会报错，提示找不strConn，为什么呢？

public class operater
{
public operater()
{
string strConn = ConfigurationManager.ConnectionStrings["ucssex_conn"].ConnectionString;
SqlConnection conn = new SqlConnection(strConn);
}
}
谢谢，用了你的方法可以了，请问我的代码为什么会不行？
strConn是非静态的字段,所以不能被引用.下面这段代码也可以.
public class operater
{
static string strConn = ConfigurationManager.ConnectionStrings["ucssex_conn"].ConnectionString;
SqlConnection conn = new SqlConnection(strConn);
}
非常感谢！
