我有个问题 。当我在我的网站项目（.net 4.0 aspx webform）上尝试使用贝宝付款（rest api & PaypalCoreSDK 版本为 1.3.4.0，RestApiSDK 版本为 0.7.3.0）时，我遇到了问题，错误消息。但有时运行平稳此消息是；

        catch (PayPal.Exception.PayPalException ex)
        {
            //Response.Write(ex.Message);
        }

        Response.Redirect(redirectUrl);

你能快点帮我吗？谢谢。

我遇到了同样的问题。对我来说，它原来是由交易描述中的某些字符和交易中的项目引起的。例如。“欧元符号”、á é ä 等等。

似乎库没有（正确）处理此编码。

简是完全正确的，感谢您的重要领导。

自从上周使用新的付款表格上线以来，我一直在为这个偶尔出现的错误苦苦挣扎几天。事实证明，许多国际地址包含包含变音符号的字母（http://en.wikipedia.org/wiki/Diacritic）。我通过在我的帖子数据中使用这些字符在贝宝沙箱中确认了这个问题，并反复得到你上面描述的确切错误。我也在使用您上面描述的相同库。

为了尝试解决这个问题（到目前为止在所有测试中都有效），我正在以下方法中清理我的用户输入（地址行 1、行 2、first_name、last_name 等）

    // http://msdn.microsoft.com/en-us/library/ebza6ck1.aspx
    String NormalizeString(String value)
    {
        if (!value.IsNullOrEmpty())
        {
            var newStringBuilder = new StringBuilder();
            newStringBuilder.Append(value.Normalize(NormalizationForm.FormKD)
                                            .Where(x => x < 128)
                                            .ToArray());
            return newStringBuilder.ToString();
        }

        return value;
    }
