Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说
c#获取数据类型_属性名是什么,希望能够帮助你!!!。

#region 生成Type类的对象：方式一 Type type = typeof(Student); #endregion #region 生成Type类的对象：方式二 Type typeStudent2 = new Student().GetType(); #endregion

1、调用

public void Get() { User model = new User { user_name = "admin", nick_name = "king", password = "" }; string result = GetProperties(model); string value = GetPropertyValue(model, "user_name"); }

2、实体类

public class User { public string user_name { get; set; } public string nick_name { get; set; } public string password { get; set; } }

3、PropertyInfo 获取实体类的所有属性和值

public string GetProperties<T>(T t) { string tStr = string.Empty; if (t == null) { return tStr; } PropertyInfo[] properties = t.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public); if (properties.Length <= 0) { return tStr; } foreach (PropertyInfo item in properties) { string name = item.Name; object value = item.GetValue(t, null); if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String")) { tStr += string.Format("{0}:{1},", name, value); } else { GetProperties(value); } } return tStr; }

4、PropertyInfo 获取实体类指定属性值

public string GetPropertyValue<T>(T t, string field) { string value = "9"; if (t == null) { return value; } PropertyInfo[] properties = t.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public); if (properties.Length <= 0) { return value; } var property = properties.Where(x => x.Name == field).FirstOrDefault(); value = property.GetValue(t, null).ToString(); return value; }

5、类型判断
propertyInfo.PropertyType != typeof(int)
propertyInfo.PropertyType != typeof(double)
propertyInfo.PropertyType != typeof(DateTime?)

 private readonly TestDbContext _context; public ReportsService(TestDbContext context) { _context = context; } public IEnumerable<TestDto> Get() { _context.ExecuteProc<TestDto>("存储过程名称", 参数); } public static IEnumerable<TElement> ExecuteProc<TElement>(this TestDbContext db, string sql, params object[] parameters) where TElement : new() { var connection = db.Database.GetDbConnection(); using (var cmd = connection.CreateCommand()) { db.Database.OpenConnection(); cmd.CommandText = sql; cmd.CommandType = System.Data.CommandType.StoredProcedure; cmd.Parameters.AddRange(parameters); var dr = cmd.ExecuteReader(); var columnSchema = dr.GetColumnSchema(); var data = new List<TElement>(); while (dr.Read()) { TElement item = new TElement(); Type type = item.GetType(); foreach (var kv in columnSchema) { var propertyInfo = type.GetProperty(kv.ColumnName); if (kv.ColumnOrdinal.HasValue && propertyInfo != null) { if (kv.ColumnName == "COLLECTOR_CODE") { } var value = dr.IsDBNull(kv.ColumnOrdinal.Value) ? null : dr.GetValue(kv.ColumnOrdinal.Value); if (value == null) { } else { if (!string.IsNullOrEmpty(value.ToString()) && propertyInfo.PropertyType != typeof(int) && propertyInfo.PropertyType != typeof(double) && propertyInfo.PropertyType != typeof(DateTime?)) { value = value.ToString(); } } propertyInfo.SetValue(item, value); } } data.Add(item); } dr.Dispose(); return data; } }
