SQLServer数据库:获取列标题(字段名)

写数据库之前最好先查看数据库字段名是否存在，否则很容易出现写数据库失败。

SqlConnection ^SqlServer_con;			//SqlServer

		Form1(void)
		{
			InitializeComponent();
			//
			//TODO: 在此处添加构造函数代码
			//

			
			this->SqlServer_con = gcnew SqlConnection();
			//this->SqlServer_con->ConnectionString = "server=(local);database=temp;uid=sa;pwd=!QAZ@WSX#EDC";
			this->SqlServer_con->ConnectionString = "server=(local);database=test;uid=sa;pwd=123456";
			try
			{
				this->SqlServer_con->Open();
			}
			catch (System::Exception^ e)
			{
				System::Windows::Forms::MessageBox::Show("链接数据库失败!", "错误", System::Windows::Forms::MessageBoxButtons::OK,
					System::Windows::Forms::MessageBoxIcon::Error);
				return;
			}

			SqlCommand ^SqlServer_cmd;			//SqlServer
			SqlDataReader ^reader;

			try
			{
				SqlServer_cmd = gcnew SqlCommand("SELECT TOP 1 * FROM [sl651_2014]", this->SqlServer_con);			//SqlServer
				reader = SqlServer_cmd->ExecuteReader();
				for (int i = 0; i < reader->FieldCount;i ++)
				{
					this->textBox1->Text += ""+(i+1)+"t"+reader->GetName(i)->ToString()+"rn";
				}
			}
			catch (System::Exception^ e)
			{

			}

			reader->Close();
			this->SqlServer_con->Close();
		}

使用 reader->GetName(i)即可获取到指定列的字段名称
reader->FieldCount即为列数量
