UC知道C# button1_Click(sender, e);出现死循环点确定

private void frmMain_Load(object sender, EventArgs e)
{
//加载所有的服务器名称
getSQLServer();
cbbSqlServerName.SelectedIndex = 0;
}
private void getSQLServer()
{
SQLDMO.Application SQLServer = new SQLDMO.Application();
SQLDMO.NameList strServerList = SQLServer.ListAvailableSQLServers();
if (strServerList.Count > 0)
{
for (int i = 0; i < strServerList.Count; i++)
{
cbbSqlServerName.Items.Add(strServerList.Item(i+1));
}
}
}
private void button1_Click(object sender, EventArgs e)
{
try
{
cbbSqlData.Items.Clear();
SqlConnection conn = new SqlConnection("Persist Security Inf
{
//加载所有的服务器名称
getSQLServer();
cbbSqlServerName.SelectedIndex = 0;
}
private void getSQLServer()
{
SQLDMO.Application SQLServer = new SQLDMO.Application();
SQLDMO.NameList strServerList = SQLServer.ListAvailableSQLServers();
if (strServerList.Count > 0)
{
for (int i = 0; i < strServerList.Count; i++)
{
cbbSqlServerName.Items.Add(strServerList.Item(i+1));
}
}
}
private void button1_Click(object sender, EventArgs e)
{
try
{
cbbSqlData.Items.Clear();
SqlConnection conn = new SqlConnection("Persist Security Inf
catch
{
button1_Click(sender, e);
}
就是这里错了，只要不成功就调用自己，还不成功就调用自己，一直下去.....
for (int i = 0; i < strServerList.Count; i++)
{
cbbSqlServerName.Items.Add(strServerList.Item(i+1));
}
里面的item索引是方括号吧？还有，为什么是i+1呢？不会引起越界的异常吗？
建议在代码的最后添加finally{conn.close();}语句。
前面代码报错，跳到catch块，然后你又
catch
{
button1_Click(sender, e);
}
又执行click事件，又报错，又catch… 于是死循环
