找不到类型或命名空间名称“LogMsgType”（您是否缺少using指令或程序集引用？） [英] The type or namespace name 'LogMsgType' could not be found (are you missing a using directive or an assembly reference?)

问题描述

大家好，



i正在使用c＃开发Windows应用程序项目。



在我的申请中得到两个错误，实际上我已经尝试了很多方法，但我在下面的代码中找到了它发生的事情。



我的错误是：



无法找到类型或命名空间名称''LogMsgType''（您是否缺少using指令或汇编引用？）



找不到类型或命名空间名称''DataMode''（您是否缺少using指令或汇编引用？）







我的代码是：

hi all,

i am developing windows application project using c#.

in my application am getting two errors, actually i had tried many ways but i coudnt find what it as happen in my code below.

my errors are:

The type or namespace name ''LogMsgType'' could not be found (are you missing a using directive or an assembly reference?)

The type or namespace name ''DataMode'' could not be found (are you missing a using directive or an assembly reference?)



my code is:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using CSOCR.Properties;
using System.Text;
using System.IO;
using System.Windows.Forms;
using System.IO.Ports;
using System.Threading;

namespace CSOCR
{
    public partial class Form1 : Form
    {

        // The main control for communicating through the RS-232 port
        private SerialPort comport = new SerialPort();

        // Various colors for logging info
        private Color[] LogMsgTypeColor = { Color.Blue, Color.Green, Color.Black, Color.Orange, Color.Red };
        
        // Temp holder for whether a key was pressed
        private bool KeyHandled = false;

        private Settings settings = Settings.Default;
        public Form1()
        {
            // Load user settings
            settings.Reload();

            // Build the form
            InitializeComponent();

            // Restore the users settings
            InitializeControlValues();

            // Enable/disable controls based on the current state
            EnableControls();

            // When data is recieved through the port, call this method
            comport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
            comport.PinChanged += new SerialPinChangedEventHandler(comport_PinChanged);
        }
      
       
              
        private void Log(LogMsgType msgtype, string msg)           //  this is my first error
        {
            rtfTerminal.Invoke(new EventHandler(delegate
            {
                rtfTerminal.SelectedText = string.Empty;
                rtfTerminal.SelectionFont = new Font(rtfTerminal.SelectionFont, FontStyle.Bold);
                rtfTerminal.SelectionColor = LogMsgTypeColor[(int)msgtype];
                rtfTerminal.AppendText(msg);
                rtfTerminal.ScrollToCaret();
            }));
        }
       
        private DataMode CurrentDataMode                        // this is my second error
        {
            get
            {
                if (rbHex.Checked) return DataMode.Hex;
                else return DataMode.Text;
            }
            set
            {
                if (value == DataMode.Text) rbText.Checked = true;
                else rbHex.Checked = true;
            }
        }
    }
}

请查看上面的代码，让我知道我错误的地方我的代码，以便我可以纠正我的错误。



提前感谢。

please find out my code above and let me know where i did mistake in my code,so that i can rectify my mistakes.

thanks in advance.

推荐答案

具体如何解决这个问题取决于定义两个类LogMsgType和DataMode的位置：

如果它们在同一个项目中，但在不同的命名空间中，则需要使用语句添加。

如果它们在不同的项目或外部DLL中，您需要对项目/ DLL的引用和使用语句。



将光标放在两个类名之一中，开头会出现一条蓝线。将鼠标悬停在蓝线上，会出现一个下拉列表。打开下拉菜单。

如果它包含两个解决方案（使用解决方案和完全限定名称），那么您可能需要使用语句，所以选择那个。如果包含两个解决方案（为''xxx''生成类和生成新类型...），那么您还需要添加引用。

Exactly how you fix this depends on where the two classes "LogMsgType" and "DataMode" are defined:
If they are within the same project, but in a different namespace then you need to add a using statement.
If they are in a different project, or in an external DLL, then you need both a reference to the project/DLL and a using statement.

Put your cursor in one of the two class names, and a blue line will appear at the beginning. Hover the mouse over the blue line and a drop down will appear. Open the drop down.
If it contains two solutions (a "using" solution and a fully qualified name) then you probably need a using statement, so select that. If is contains two solutions ("Generate class for ''xxx''" and "Generate new type...") then you need to add a reference as well.
