ArgumentException: 从索引 29 处开始,初始化字符串的格式不符合规范.

我自己写的是这样的 点击登陆按钮
SqlConnection con = new SqlConnection("server=(local);database=xzgw;uid:sa;pwd:123;");
con.Open();
string sqlStr = "select count(*) from [user] where username='" + TextBox1.Text + "'and password='" + TextBox2.Text + "'";
SqlCommand com = new SqlCommand(sqlStr, con);
int result = (int)com.ExecuteScalar();
if (result > 0)
Response.Redirect("Default.aspx");

else
Response.Write("<script>alert('用户名或密码错误！')</script>");
con.Close();

SqlConnection con = new SqlConnection("server=(local);database=xzgw;uid=sa;pwd=123");

中间是等于，不是冒号
