尝试创建新对象时，格式字符串的格式不正确
本文关键字：格式 字符串 不正确 对象 创建 新对象 | 更新日期: 2023-09-27 18:17:43
我有一个可以创建产品的方法。但是当我将不同的输入转换为正确的格式时，我得到一个错误。
错误如下
[FormatException: string is not in a correct format.]System.Number。stringtonnumber(字符串str, NumberStyles选项，NumberBuffer&number, NumberFormatInfo info, Boolean parseDecimal) +12099621System.Number。ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +120System.Convert。ToInt32(字符串值)+44EPWebApp.NewProduct。btnSaveNewItem_Click(对象发送者，EventArgs e) in d:'Europoultry'Program'EPWCF'EPSystem'EPWebApp'NewProduct.aspx.cs:450System.Web.UI.WebControls.Button。OnClick(EventArgs e) +9671538System.Web.UI.WebControls.Button。RaisePostBackEvent(String eventArgument) +108System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler。RaisePostBackEvent(String eventArgument) +12System.Web.UI.Page。RaisePostBackEvent(ipostbackeventandler sourceControl, String eventArgument) +15System.Web.UI.Page。RaisePostBackEvent(NameValueCollection postData) +35System.Web.UI.Page。ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1639

}
我检查了方法得到的所有参数，它们都应该是正确的格式
答案保留在异常中。
调用Converter类的方法，在该方法中尝试解析一个无效的字符串，因为其中有一些非数字(特殊字符，字母)字符。
可以尝试转换try-catch块中的值。
try
{
//your method call
}
catch(FormatException ex)
{
//some handling
}
