我尝试过以下方法
this.Cursor = Cursors.WaitCursor; //OR
this.UseWaitCursor = true; //OR
Application.UseWaitCursor = true; //OR
Application.DoEvents(); //AND

,但显然当添加以下行时等待光标没有显示:
this.Enabled = false;

P/S:this
指窗口形式。
问题:
如何将 WaitCursor 光标设置在禁用的 WinForms 上?
您应该以不同的方式处理事情...不应该有理由禁用表单来阻止用户交互。使用带有进度条或消息的对话框,让用户知道发生了什么。不要给用户留下程序挂起或崩溃的印象。这是一条可怕的路线。从用户的角度思考一下,当您使用其他程序时,是什么让您感到沮丧。
然而,这对我有用:
this.Enabled = false;
this.UseWaitCursor = true;

显然,它仅在光标位于表单上时显示。
这是完整的测试代码:
namespace WindowsFormsApplication1
{
partial class Form1
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
this.button1.Location = new System.Drawing.Point(163, 110);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(284, 262);
this.Controls.Add(this.button1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
this.Enabled = false;
this.UseWaitCursor = true;
}
private System.Windows.Forms.Button button1;
}
}
