如何获取数据集的字段名称 [英] How to get field names of a dataset

问题描述

我的数据集如下：

I have a data set as follows:

namespace user_control_typed_dataset
{


   partial class Studentdataset
   {

        public string Name{get;set;}
        public string ID { get; set; }
        public string Address { get; set;}

        private void InitializeComponent()
        {


        }

    }
}

i想要打印字段名称Name，ID和Address.But当我使用字段信息属性时，我也得到了很多其他字段和名称，我得到< name> backing_field.But我只想要名字。如何解决这个问题。请帮助我。

推荐答案

这是一个小例子给你



DataTable table = new DataTable（）;

table.Columns.Add（Employee，typeof（string））;

table.Columns .Add（ID，typeof（string））;



table.Rows.Add（Xing Zuber，1）;

table.Rows.Add（Daving solman，2）;

table.Rows.Add（Iyan Yokovich，3）;

table.Rows.Add（Dev richardson，4）;

table.Rows.Add（Jeanson，5）;



string [] columnNames = table.Columns.Cast< datacolumn>（）

.Select（x => x.ColumnName）

.ToArray（）;





foreach（stringNames中的字符串dc）

{

string st = dc.ToString（）;

}

Here is a small example for you

DataTable table = new DataTable();
table.Columns.Add("Employee", typeof(string));
table.Columns.Add("ID", typeof(string));

table.Rows.Add("Xing Zuber", "1");
table.Rows.Add("Daving solman", "2");
table.Rows.Add("Iyan Yokovich", "3");
table.Rows.Add("Dev richardson", "4");
table.Rows.Add("Jeanson ", "5");

string[] columnNames = table.Columns.Cast<datacolumn>()
.Select(x => x.ColumnName)
.ToArray();


foreach (string dc in columnNames)
{
string st = dc.ToString();
}

Studentdataset student = new Studentdataset();
studentProperties = student.GetType().GetProperties();
foreach (var propertyInfo in studentProperties)
{
  Consol.WriteLine(propertyInfo.Name);
}
