解决方案
请写下波纹管功能Button1下的ChangePassword（）点击
这将适用于更改密码。如果有任何错误，请告诉我。
私人 void ChangePassword（）
{
尝试
{
con.Open（）;
SqlDataAdapter da = new SqlDataAdapter（ select *来自tbllogin wherere username =' + txtUsername.Text + '，con ）;
DataSet ds = new DataSet（）;
da.Fill（ds）;
con.Close（）;
string username = ds.Tables [ 0 ]。行[ 0 ] [ 1 ]。ToString（）;
string OLdpassword = ds.Tables [ 0 ]。行[ 0 ] [ 2 ]。ToString（）;
if （OLdpassword == txtOLDPassword.Text）
{
if （txtNewPassword.Text == txtConfirmPassword.Text）
{
con.Open（）;
SqlCommand cmd = new SqlCommand（ update tbllogin set password =' + txtNewPassword.Text + 'where username =' + txtUsername.Text + '）;
int querystatus = cmd.ExecuteNonQuery（）;
if （querystatus > 0 ）
{
lblError.ForeColor = System.Drawing.Color.Green;
lblError.Text = 密码已成功更新;
}
else
{
lblError.ForeColor = System.Drawing.Color.Red;
lblError.Text = 执行错误;
}
}
else
{
lblError.ForeColor = System.Drawing.Color.Red;
lblError.Text = 密码未命中匹配;
}
}
else
{
lblError.ForeColor = System.Drawing.Color.Red;
lblError.Text = 旧密码不正确;
}
}
catch {}
最后 {con.Close（）; }
}

如果你想更改密码作为你的设计，只需获取3个文本框值，首先使用db检查当前密码，然后比较新传递和确认传递，然后在用户表中更新。
如果你想要重置密码，你需要获取新的密码和用户的电子邮件地址，检查电子邮件地址是否正确与db，并在db中更新新密码，并通过邮件发送新的密码，bca你有用户的电子邮件地址。
以上2种方式你可以使用，一切都很简单，只需选择查询，比较值和更新值，在你的项目中你使用所有查询为什么你需要编码，只需使用你的exesting查询和chnage一点点。

Hi,
Please write the bellow function "ChangePassword()" under Button1 click
This will work for the changing password.If any error comes please let me know.
private void ChangePassword() { try { con.Open(); SqlDataAdapter da = new SqlDataAdapter("select * from tbllogin wherere username='" + txtUsername.Text + "'", con); DataSet ds = new DataSet(); da.Fill(ds); con.Close(); string username=ds.Tables[0].Rows[0][1].ToString(); string OLdpassword=ds.Tables[0].Rows[0][2].ToString(); if (OLdpassword == txtOLDPassword.Text) { if (txtNewPassword.Text == txtConfirmPassword.Text) { con.Open(); SqlCommand cmd = new SqlCommand("update tbllogin set password='" + txtNewPassword.Text + "' where username='" + txtUsername.Text + "'"); int querystatus = cmd.ExecuteNonQuery(); if (querystatus > 0) { lblError.ForeColor = System.Drawing.Color.Green; lblError.Text = "Password updated successfully"; } else { lblError.ForeColor = System.Drawing.Color.Red; lblError.Text = "Execution error"; } } else { lblError.ForeColor = System.Drawing.Color.Red; lblError.Text = "Password miss match"; } } else { lblError.ForeColor = System.Drawing.Color.Red; lblError.Text = "Old password is incorrect"; } } catch { } finally { con.Close(); } }

If u want to change password as ur design,just get 3 text box values,first check with current password with db and then compare new pass and confirm pass and then update in user table.
If u want to reset password,u need to get new password and user email address,check email address is correct or not with db,and update new password in db and also send new pass word via mail,bca u have user email address.
The above 2 way u can use,all are easy ,just select query ,compare values and update values,in ur project u use all queries why u need codings,just use ur exesting query and chnage little bit.
