Asp.net mvc 在DotNet应用程序中使用DocuSign时出错

我正在我的应用程序中实现DocuSign功能来签署PDF。 我正在浏览以下链接： 我们可以在使用上述链接中提到的步骤时在PDF中添加签名，但在第二次调用相同的方法对新PDF进行签名时，我们会在CreateEnvelope行收到错误消息

错误响应：{errorCode:UNSPECIFIED_错误，消息： 输入字符串的格式不正确。}

它在创建信封时生成错误。在这条线上

由于长度不受支持，我们已删除base 64字符串。

请确保正确传递signHere.XPosition和signHere.YPosition值

以下语句的计算结果可能为十进制值。确保它是一个整数

signHere.YPosition = (height - Convert.ToInt32(fieldPosition.position.Top + 25)).ToString();

故障排除步骤

---

请运行EnvelopedDefinition.ToJson Sdk并确保发布到DocuSign api的最终Json是正确的。

请添加您的代码。请澄清您的具体问题或添加其他详细信息，以突出显示您所需的内容。正如目前所写的，很难准确地说出你在问什么。请参阅页面以获取澄清此问题的帮助。XPosition和YPosition的最终值是什么？能否在envelopesApi.CreateEnvelope语句之前运行此envDef.ToJson并将json发布到问题中。嗨，团队，我找到了解决方案。实际上，在我们的例子中，Y位置是作为十进制值。我们已将十进制数四舍五入，现在运行良好。

signHere.YPosition = (height - Convert.ToInt32(fieldPosition.position.Top + 25)).ToString();
