【问题描述】：

我发现了一个类似的问题，但答案仅有助于显示其中一个滚动条。

我的表单有一个 SplitContainer。在其中一个面板 (Panel2) 中有一个 PictureBox，其中包含我要显示的图像。

我需要找到一种方法，当图像超过面板大小时，使垂直和水平滚动条都出现。

我已经将 AutoScroll 设置为 true，并且我发现有必要将 Anchor 设置在左侧以显示其中一个滚动条，并将 Anchor 设置在 Top 以显示另一个，但我需要它们。

提前致谢。

【问题讨论】：

所以将锚点设置在顶部和左侧，而不是底部或右侧

【参考方案1】：

确保您嵌入 PictureBox 的 SplitContainer.Panel 将 AutoScroll 属性设置为 True 并且您的 PictureBox 的 SizeMode 属性设置为 'AutoSize' (PictureBoxSizeMode.AutoSize)。

希望我能帮到你:)

【参考方案2】：

我在设置这样的东西时没有发现任何问题。这是我的设计器代码：

partial class Form1

    /// <summary>
    /// Required designer variable.
    /// </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 Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()

        this.pictureBox1 = new System.Windows.Forms.PictureBox();
        ((System.ComponentModel.ISupportInitialize)(this.splitContainer1)).BeginInit();
        this.splitContainer1.Panel2.SuspendLayout();
        this.splitContainer1.SuspendLayout();
        ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
        this.SuspendLayout();
        // 
        // splitContainer1
        // 
        this.splitContainer1.Dock = System.Windows.Forms.DockStyle.Fill;
        this.splitContainer1.Location = new System.Drawing.Point(0, 0);
        this.splitContainer1.Name = "splitContainer1";
        // 
        // splitContainer1.Panel2
        // 
        this.splitContainer1.Panel2.AutoScroll = true;
        this.splitContainer1.Panel2.Controls.Add(this.pictureBox1);
        this.splitContainer1.Size = new System.Drawing.Size(576, 406);
        this.splitContainer1.SplitterDistance = 192;
        this.splitContainer1.TabIndex = 0;
        // 
        // pictureBox1
        // 
        this.pictureBox1.Image = global::WinFormsScratch.Properties.Resources.Desert;
        this.pictureBox1.Location = new System.Drawing.Point(0, 0);
        this.pictureBox1.Name = "pictureBox1";
        this.pictureBox1.Size = new System.Drawing.Size(1024, 768);
        this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;
        this.pictureBox1.TabIndex = 0;
        this.pictureBox1.TabStop = false;
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(576, 406);
        this.Controls.Add(this.splitContainer1);
        this.Name = "Form1";
        this.Text = "Form1";
        this.splitContainer1.Panel2.ResumeLayout(false);
        this.splitContainer1.Panel2.PerformLayout();
        ((System.ComponentModel.ISupportInitialize)(this.splitContainer1)).EndInit();
        this.splitContainer1.ResumeLayout(false);
        ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();
        this.ResumeLayout(false);
