属性 值无效 - GDI+ 中发生一般性错误

Question

我正在尝试 运行 一个 10 年前的 C# Visual Studio 项目

出于某种原因，我无法删除或编辑表单中的任何图像

如果我在使用视图设计器时尝试编辑 PictureBox 的图像 属性，我会收到 "Property value is not valid" 错误。详细信息框显示为 "A generic error occurred in GDI+."

即使更改 PictureBox 的大小也会触发相同的错误

虽然不是那么相关，但这是表单的代码。在我看来，这只是视图设计器自动生成的代码：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Threading;

namespace AppCliente.Vista
{
    public class frmLogin : System.Windows.Forms.Form
    {
        private System.Windows.Forms.PictureBox picLogin;
        private System.ComponentModel.Container components = null;

        private frmLogin()
        {           
            InitializeComponent();      
        }

        private void InitializeComponent()
        {
            this.picLogin = new System.Windows.Forms.PictureBox();
            ((System.ComponentModel.ISupportInitialize)(this.picLogin)).BeginInit();
            this.SuspendLayout();
            // picLogin
            // 
            this.picLogin.Location = new System.Drawing.Point(-1, -3);
            this.picLogin.Name = "picLogin";
            this.picLogin.Size = new System.Drawing.Size(264, 48);
            this.picLogin.TabIndex = 5;
            this.picLogin.TabStop = false;
            this.picLogin.Click += new System.EventHandler(this.picLogin_Click);       
            this.Controls.Add(this.picLogin); 
            ((System.ComponentModel.ISupportInitialize)(this.picLogin)).EndInit();

        }


        private void picLogin_Click(object sender, EventArgs e)
        {

        }
    }
}

可能是什么原因造成的？

如果有用，我在尝试编译项目时会收到​​以下错误：

将目标框架更改为 .Net 2.0 后，我开始收到更多有意义的错误消息 原来各种形式的.resx文件都损坏了，所以删除它们解决了问题
