C# 工具类

Dns获取本机IP地址

public static string GetLocalIP()
{
	try
	{
		string HostName = Dns.GetHostName(); //得到主机名
		IPHostEntry IpEntry = Dns.GetHostEntry(HostName);
		for (int i = 0; i < IpEntry.AddressList.Length; i++)
		{
			//从IP地址列表中筛选出IPv4类型的IP地址
			//AddressFamily.InterNetwork表示此IP为IPv4,
			//AddressFamily.InterNetworkV6表示此地址为IPv6类型
			if (IpEntry.AddressList[i].AddressFamily == AddressFamily.InterNetwork)
			{
				return IpEntry.AddressList[i].ToString();
			}
		}
		return "";
	}
	catch (Exception ex)
	{
		MessageBox.Show("获取本机IP出错:" + ex.Message);
		return "";
	}
}

获取当前项目App.config文件下的value值

//获取当前项目App.config文件下的 key=ActiveMQURL 的value值
<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<appSettings>
		<add key="ActiveMQURL" value="tcp://xxxxx:xxxx" />
	</appSettings>
</configuration>

string url = System.Configuration.ConfigurationManager.AppSettings["ActiveMQURL"];

//获取+验证
if (ConfigurationManager.AppSettings["CameraDirver"].ToUpper() == "TOUPCAM")
{
	
}

将枚举值赋值到下拉文本框中

//将枚举值赋值到下拉文本框中
//定义静态方法进行转换
public static List<Item> EnumToList<T>()
{
	List<Item> ret = new List<Item>();
	foreach (Enum item in Enum.GetValues(typeof(T)))
	{
		Item it = new Item();
		it.Value = item;
		it.Name =Enum.GetName(typeof(T),item);
		ret.Add(it);
	}
	return ret;
}

//枚举声明
public enum SexType
{
	女=0,
	男=1
}

//第一种转换方式
tSex.DataSource = CommUtils.Bind.BindUtils.EnumToList<PQCS.Enums.SexType>();

//
[Serializable]
public class Item
{
	public string Name { get; set; }
	public Object Value { get; set; }
}

读取Json文件

public HttpService HttpService { get; set; } //

public LogService()
{
	Dictionary<String, String> keyValuePairs = LocalStorage.DeserializeJSON<Dictionary<String, String>>("LogConfig");
	if (true)
	{
		keyValuePairs = new Dictionary<string, string>();
		keyValuePairs.Add("logServiceUrl", "http://xxxxxx:xxxxx");
		//keyValuePairs.Add("logServiceUrl", "http://localhost:8080");
		LocalStorage.SerializeJSON(keyValuePairs, "LogConfig");
	}
	this.HttpService = new HttpService();
	this.HttpService.HostUrl = keyValuePairs["logServiceUrl"];//HostUrl string属性
}

JSON转换

public static T DeserializeJSON<T>(string name)
{
	byte[] data = ReadFile(name);
	if (data != null)
	{
		string text = Encoding.Default.GetString(data);
		object obj = Newtonsoft.Json.JsonConvert.DeserializeObject(text, typeof(T));
		return (T)obj;
	}
	else
	{
		return default(T);
	}
}

public static void SerializeJSON(Object obj, string name)
{
	string s = Newtonsoft.Json.JsonConvert.SerializeObject(obj);
	byte[] data = Encoding.Default.GetBytes(s);
	SaveFile(data, name);
}

使用文件流的方式，向文档中添加数据

FileStream 文件流 = new FileStream(蜡块打印路径, FileMode.Create, FileAccess.Write);//搜索创建写入文件 
StreamWriter sw = new StreamWriter(文件流, Encoding.Default);//sw(流作者)文件流编码默认
int 蜡块总数 = Convert.ToInt32(totalSample.Text);//起始值(蜡块数量)
int 材料数量 = Convert.ToInt32(totalL.Text);//结束值(材料数量)
int 取材次数 = 材料数量 - 蜡块总数;
string 病理号 = CurrentCaseViewModel.CaseNO;
if (取材次数 <= 0)
{
	if (材料数量 > 0)
	{
		sw.Write(病理号 + "-" + 材料数量.ToString());
	}
	else
	{
		sw.Write(病理号);
	}
	sw.Close();
	文件流.Close();
}

将数据写入指定路径文件中

string timestr = DateTime.Now.ToString("yyMMddHHmmssfff");
//写入第一个文件夹
string path = "C:\\" + fileName + "\\" +timestr + "-" + model.CaseNo+"-" + model.Number + ".txt";
FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write);//搜索创建写入文件
StreamWriter sw = new StreamWriter(fs, Encoding.UTF8);
sw.Write(model.CaseNo + "," + model.Number + "," + model.Type + "\r\n");
sw.Dispose();

检查文件是否存在，不存在时进行创建

string fileFolder = "C:\\" + fileName;
if (!Directory.Exists(fileFolder))
{
    Directory.CreateDirectory(fileFolder);
}

Json转换为对象

StreamReader file = File.OpenText(Environment.CurrentDirectory + "\\UpdateList.json");
Newtonsoft.Json.JsonTextReader reader = new Newtonsoft.Json.JsonTextReader(file);
 Newtonsoft.Json.JsonSerializer serializer = new Newtonsoft.Json.JsonSerializer();
 object obj = serializer.Deserialize(reader, typeof(List<UpdateConfig>));
 工作站List = obj as List<UpdateConfig>;
