我已經(jīng)創(chuàng)建了這段代碼在 .dll 文件中創(chuàng)建表單并添加控件 TextBox dbname = new TextBox(); dbname.BorderStyle = BorderStyle.Fixed3D; dbname.Location = new Point(236, 81); Button Create = new Button(); Create.FlatStyle = FlatStyle.Flat; Create.FlatAppearance.BorderSize = 0; Create.Location = new Point(261, 115); Create.Text = "Create"; Create.Click += new System.EventHandler(this.Create_Click);如何從文本框中獲取文本？private void Create_Click(object sender , EventArgs e) { SaveFileDialog _sfd_ = new SaveFileDialog(); _sfd_.Filter = "Housam Printing |*.HP"; _sfd_.InitialDirectory = AppDomain.CurrentDomain.BaseDirectory; _sfd_.FileName = dbname.text; _sfd_.Title = "Database location"; }

為了使您的控件可供類的其他成員訪問(wèn)，您需要在類級(jí)別定義它們。Form_Load然后您可以在構(gòu)造函數(shù)或事件（或任何您想要的地方）中初始化它們，并可以從其他類方法訪問(wèn)它們：
public partial class Form1 : Form
{
// Declare your controls at the class level so all methods can access them
private TextBox dbName;
private Button create;
private void Form1_Load(object sender, EventArgs e)
{
dbName = new TextBox
{
BorderStyle = BorderStyle.Fixed3D,
Location = new Point(236, 81)
};
Controls.Add(dbName);
create = new Button
{
FlatStyle = FlatStyle.Flat,
Location = new Point(261, 115),
Text = "Create",
};
create.FlatAppearance.BorderSize = 0;
create.Click += create_Click;
Controls.Add(create);
}
private void create_Click(object sender , EventArgs e)
{
var sfd = new SaveFileDialog
{
Filter = "Housam Printing |*.HP",
InitialDirectory = AppDomain.CurrentDomain.BaseDirectory,
FileName = dbName.Text,
Title = "Database location"
};
}
}
