FIX: System.FormatException when you run a Visual Studio 2010 application that calls the DataSet.ReadXmlSchema method

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You run an application that is created by using Microsoft Visual Studio 2010.
  • You call the DataSet.ReadXmlSchema method to read an XML schema into a DataSet object.
  • You set the Negative sign symbol setting to a symbol other than the minus sign ("-") in the Number tab of the Customize Format dialog box.

    Note The Customize Format dialog box is in the Regional and Language settings of the computer.
In this scenario, the application encounters a System.FormatException exception and then crashes. Additionally, you may receive the following error message and stack trace information if you try to debug the application:
Input string was not in a correct format.
