using System.Data.SqlClient; namespace SchemaInfo { public partial class FrmSchemaInfo : Form { public FrmSchemaInfo() { InitializeComponent(); dgvSchemaInfo.AutoGenerateColumns = false; } private void btnShow_Click(object sender, EventArgs e) { string ConnString = @"Data Source=.\sql2016;Initial Catalog=AdventureWorks2016CTP3;Integrated Security=True;"; using (SqlConnection conn = new SqlConnection(ConnString)) { SqlCommand cmd = new SqlCommand("SELECT * FROM HumanResources.Employee", conn); conn.Open(); using (SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.KeyInfo)) { DataTable SchemaTable = reader.GetSchemaTable(); dgvSchemaInfo.DataSource = SchemaTable; }; } } } }只列出和 SqlDataAdapter.FillSchema() 有差異,覺得用的到欄位資訊喔

[ADO] Schema 資訊
利用 SqlDataAdapter.FillSchema() 填入 DataTable Schema 資訊,仔細確認才發現到 DataColumn 內沒有 SqlDbType 資訊,要利用 Command.ExecuteReader(CommandBehavior.KeyInfo) 才會有 SqlDbType 資訊
