Question

已经找到了这个问题的一些答案，但似乎没有一个适合我的情况。我无法弄清楚什么是错的或如何解决它。我试图在统一中使用PDFsharp并且它给了我上面的错误，这是提出问题的代码：

using System;
using System.Diagnostics;
using System.Drawing;
using System.Drawing.Drawing2D;
using PdfSharp.Drawing;

{
/// <summary>

  this.properties = XGraphicsLab.properties;
}

public virtual void RenderPage(XGraphics gfx)
{
  //Debug.WriteLine("RenderPage");
  //gfx.Clear(this.properties.General.BackColor.Color);
  //DrawGridlines(gfx);
  gfx.SmoothingMode = XSmoothingMode.AntiAlias;
}

感谢您对此有所了解！

同一个名称空间中有两个类同名。

您有 XDrawing.TestLab.Tester 作为命名空间， TesterBase 是编译器抱怨的类名。您需要查看项目中的每个.CS文件，并确保它们 NOT 具有名为 TesterBase 的任何类。

名称空间`XDrawing.TestLab.Tester'已包含`TesterBase'的定义
