我在C#
中使用以下代码连接到我的SQL Server,它运行正常。但我想向用户显示一条消息,说如果连接成功与否,并且不知道如何做到这一点。有谁可以帮助我?
这是我的代码:
string cs = "Data Source=IS020114\\CODRINMA;Initial Catalog=gcOnesti;Integrated Security=True";
private void conectareToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
using (SqlConnection con = new SqlConnection(cs))
{
con.Open();
}
}
catch (Exception er) {
MessageBox.Show(er.Message);
}
}

您自己提供了答案。请尝试以下代码:
string cs = "Data Source=IS020114\\CODRINMA;Initial Catalog=gcOnesti;Integrated Security=True";
private void conectareToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
using (SqlConnection con = new SqlConnection(cs))
{
con.Open();
MessageBox.Show("Connection successful !!");
}
}
catch (Exception er) {
MessageBox.Show("Connection unsuccessful..");
}
}

我不确定你想要什么,我不确定你是否有任何想要发布消息的控件,但是一个简单的消息框就是这样的:
string cs = "Data Source=IS020114\\CODRINMA;Initial Catalog=gcOnesti;Integrated Security=True";
private void conectareToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
using (SqlConnection con = new SqlConnection(cs))
{
con.Open();
MessageBox.Show("Yay! You're connected!");
}
}
catch (Exception er)
{
MessageBox.Show(er.Message);
}
}
