【问题描述】：

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。我真的不知道出了什么问题或如何解决它。我正在尝试统一使用 PDFsharp，它给了我上述错误，这是引发问题的代码：

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

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

感谢您对此提供的任何启发！

【问题讨论】：

这是 Unity3d 吗？您可能指的是标签中的 Unity。
是的，这是在 Unity3d 中
在项目面板中搜索 TesterBase。第二种解决方案，Shift-Cmd-F (Ctrl-Alt-F) 并输入 TesterBase。这将显示您是否由于某些原因可能有两次相同的文件或两次命名。

标签： c# unity3d namespaces

【解决方案1】：

您在同名命名空间中有两个具有同名的类。

你有 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，并确保它们没有有任何名为 TesterBase 的类。
