上面显示的代码是我想要创建的向导。Page1 和 Page2 是我使用的用户控制页面。
IPagePanel.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Wizard
{
public interface IPagePanel
{
}
}
用户控件 Page1 和 Page2 位于 2 个单独的命名空间中。
namespace Page1
{
partial class Page1
{
/// <summary>

/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.

private void InitializeComponent()
{
this.lblDescription = new System.Windows.Forms.Label();
this.SuspendLayout();
//

this.lblDescription.AutoSize = true;
this.lblDescription.Font = new System.Drawing.Font("Microsoft Sans Serif", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.lblDescription.Location = new System.Drawing.Point(228, 114);
this.lblDescription.Name = "lblDescription";
this.lblDescription.Size = new System.Drawing.Size(65, 20);
this.lblDescription.TabIndex = 0;
this.lblDescription.Text = "Page 1";
//

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.lblDescription);
this.Name = "Page1";
this.Size = new System.Drawing.Size(547, 278);
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion

}

错误 1 无法将类型“Page1.Page1”隐式转换为“Wizard.IPagePanel”。存在显式转换(您是否缺少演员表?) 21 32 向导
