关于.net的一些记录
1、HttpWebRequest调用接口
string strResult = "";
try
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://testapi.wzeye.cn/connect/token");
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
string paraUrlCoded = System.Web.HttpUtility.UrlEncode("scope");
paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(tokenscope);
paraUrlCoded += "&" + System.Web.HttpUtility.UrlEncode("grant_type");
paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(tokengranttype);
paraUrlCoded += "&" + System.Web.HttpUtility.UrlEncode("client_id");
paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(tokenclientid);
paraUrlCoded += "&" + System.Web.HttpUtility.UrlEncode("client_secret");
paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(tokenclientsecret);
try
{
byte[] payload;
//将URL编码后的字符串转化为字节
payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
//设置请求的 ContentLength
myRequest.ContentLength = payload.Length;
// 获得请 求流
Stream writer = myRequest.GetRequestStream();
//将请求参数写入流
writer.Write(payload, 0, payload.Length);
// 关闭请求流
writer.Close();
System.Net.HttpWebResponse response;
// 获得响应流
response = (System.Net.HttpWebResponse)myRequest.GetResponse();
System.IO.Stream myStream;
myStream = response.GetResponseStream();
//HttpWebResponse HttpWResp = (HttpWebResponse)myRequest.GetResponse();
//Stream myStream = HttpWResp.GetResponseStream();
StreamReader sr = new StreamReader(myStream, Encoding.UTF8);
StringBuilder strBuilder = new StringBuilder();
while (-1 != sr.Peek())
{
strBuilder.Append(sr.ReadLine());
}
strResult = strBuilder.ToString();
}
catch (Exception exp)
{
strResult = "错误：" + exp.Message;
}
}
catch (Exception exp)
{
strResult = "错误：" + exp.Message;
}
return strResult;
2、
取得控制台应用程序的根目录方法
1：Environment.CurrentDirectory 取得或设置当前工作目录的完整限定路径
2：AppDomain.CurrentDomain.BaseDirectory 获取基目录，它由程序集冲突解决程序用来探测程序集
取得WinForm应用程序的根目录方法
1：Environment.CurrentDirectory.ToString();//获取或设置当前工作目录的完全限定路径
2：Application.StartupPath.ToString();//获取启动了应用程序的可执行文件的路径，不包括可执行文件的名称
3：Directory.GetCurrentDirectory();//获取应用程序的当前工作目录
4：AppDomain.CurrentDomain.BaseDirectory;//获取基目录，它由程序集冲突解决程序用来探测程序集
5：AppDomain.CurrentDomain.SetupInformation.ApplicationBase;//获取或设置包含该应用程序的目录的名称
取得web应用程序的根目录方法
1.HttpContext.Current.Server.MapPath("~/configs/ChannelUsers.xml")
HttpContext.Current返回当前请求的 HttpContext 对象。如此我们就可以直接访问Request、Response、Session、Application等对象，和Page中访问等同。
获取网站根目录的方法有几种如：
Server.MapPath(Request.ServerVariables["PATH_INFO"])
Server.MapPath("/")
Server.MapPath("")
Server.MapPath(".")
Server.MapPath("../")
Server.MapPath("..")
Page.Request.ApplicationPath
以上的方法可以在.aspx中访问，但是如果你在winform文件就不能用。
HttpContext.Current.Server.MapPath();
System.Web.HttpContext.Current.Request.PhysicalApplicationPath在.cs文件中可以用。
但是HttpContext.Current.Server.MapPath();这个获取的是文件的路径而不是根目录。
只有System.Web.HttpContext.Current.Request.PhysicalApplicationPath 这个才是获取的根目录，在写获取数据库路径是应该用这个。
3、获得当前url
.net
string anjianurl = $"{Request.Url.Scheme}://{Request.Url.Authority}/Forms/HongYang/AnJianWeiHu.aspx?id={e.GetDataValue("ID")}&rid=1071&isapproval=true&dsd={DateTime.Now.Ticks}";
4、int、datetime转换
if(int.TryParse(no,out var iStage))
{
}
if(DateTime.TryParse(now,out var iStage))
{
}
System.Func<string, bool> getShowTask = (ID) =>
{
using (var task = new TaskDataContext())
{
return (from b in task.Task_JiHua
where b.ProjectID == ID && b.IsProject == true
&& (b.JiHuaZTText == "待执行" || b.JiHuaZTText == "执行中" || b.JiHuaZTText == "已延期" || b.JiHuaZTText == "已完成")
select new { b.ID }).ToList().Count() > 0;
}
};
5、存储临时数据
TempData["is_face"] = 1;
注意：TempData的生命周期只有一次调用，如果需要持久化，请加keep
TempData["is_face"] = 1;
TempData.Keep();
int.TryParse(TempData["is_face"].ToString(), out is_face);
TempData.Keep("is_face");
6、string 转 Enum
var t = (WaypointType)Enum.Parse(typeof(WaypointType), pointType);
7、Enum转list
public static string GetWaiPointType(WaypointType waypointType)
{
return waypointType switch
{
WaypointType.HoldEnd => "",
_ => waypointType.ToString(),
};
}
public class EnumModel
{
public string pointType { get; set; }
public string Description { get; set; }
}
public static List<EnumModel> ConvertEnumToList()
{
List<EnumModel> list = new List<EnumModel>();
foreach (var e in Enum.GetValues(typeof(WaypointType)))
{
EnumModel m = new EnumModel();
m.pointType = e.ToString();
m.Description = GetWaiPointType((WaypointType)e);
if (!string.IsNullOrWhiteSpace(m.Description))
{
list.Add(m);
}
}
return list;
}
8、加密 ：ICryptoTransform
9、string转double数组
var arr = num_str.Split(',');
var new_arr = Array.ConvertAll<string, double>(arr, s => double.Parse(s));
10、GET
JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
try
{
string apiUrl = ApiUrl + "?id=1";
// 创建请求
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(apiUrl);
request.Method = "GET";
request.ContentType = "application/json";
// 添加请求头
request.Headers.Add("appId", AppId);
// 获取响应
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
string responseText = reader.ReadToEnd();
// 核心：使用原生JavaScriptSerializer解析JSON
List<UserInfo> userList = null;
try
{
// 第一步：先反序列化为Dictionary，避开@odata.context的解析问题
Dictionary<string, object> responseDict = jsSerializer.Deserialize<Dictionary<string, object>>(responseText);
// 第二步：提取value数组（JSON中的核心数据）
if (responseDict.ContainsKey("value") && responseDict["value"] != null)
{
// 将value数组重新序列化为JSON字符串，再反序列化为UserInfo列表
string valueJson = jsSerializer.Serialize(responseDict["value"]);
userList = jsSerializer.Deserialize<List<UserInfo>>(valueJson);
return userList;
}
return null;
}
catch (ArgumentException jsonEx)
{
throw new Exception(string.Format("JSON解析失败：{0}", jsonEx.Message));
}
}
}
}
catch (Exception ex)
{
throw new Exception(string.Format("获取信息失败：{0}", ex.Message));
}
