答

首先，这完全可以正常工作:

First of all, this works perfectly fine:

Label1.Text = "Sandeep'Mewara  is a soft'ware engine'er  so'me where.";
string Gp = Label1.Text.ToString().Replace("'", "");
Gp = Gp.ToString().Replace(" ", "");

其次，您无需将Gp强制转换回字符串，因为它已经是字符串.以下是您所需要的:

Secondly, you don''t need to cast Gp back to string as it is already a string. Following is all you need:

Label1.Text = "Sandeep'Mewara  is a soft'ware engine'er  so'me where.";
string Gp = Label1.Text.ToString().Replace("'", "");
Gp = Gp.Replace(" ", "");

输出:"SandeepMewaraisasoftwareengineersomewhere."

确保您的标签传递了正确的文本.使用Visual Studio DEBUGGER查看问题所在和出处.

Output: "SandeepMewaraisasoftwareengineersomewhere."

Make sure your label has proper text passed. Use Visual studio DEBUGGER to see what and where you are going wrong.
