c# - 我如何在我的项目中解决初始化字符串的格式不符合从索引 17' 开始的规范

Question

初始化连接

System.ArgumentException:'Format of the initialization string does not conform to specification starting at index 17'

此行显示上述错误消息

    private void InitializeConnection()
    {
        server = "localhost";
        database = "table";
        uid = "root";
        password = "";
        string connectionString = "SERVER=" + server + ";" + "DATABASE" + database + ";" + "UID" + uid + ";" + "PASSWORD" + password + ";";
        ObjConnection = new MySqlConnection(connectionString); // error happens here
    }

Answer 1

在DATABASE附近的代码中应该类似于DATABASE=，UID和PASSWORD也是如此。所有你在这些变量附近都错过了=

private void InitializeConnection()
{
    server = "localhost";
    database = "table";
    uid = "root";
    password = "";
    string connectionString = "SERVER=" + server + ";" + "DATABASE=" + database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";
    ObjConnection = new MySqlConnection(connectionString);
}
