C# 在SQL Server中将varchar值转换为数据类型int时，转换失败

我犯了一个错误

将varchar值“ORB2.000000000 1”转换为数据类型int时，转换失败

你能帮我解决这个问题吗？该存储过程在开发过程中运行良好，但在另一台机器上，我遇到了该错误

varchar值在

ORB2.000000000 1

中包含一些无法转换为int的字符

ORB

。若要删除错误，请从报告字符串中删除这些字符，然后转换为int。
仅当任何字符串仅包含int（0,1,2,3,4,5,6,7,8,9）时，才能将其转换为整数

此外，如果您希望在值中使用十进制，请使用浮点数据类型。请参阅一些c#

的数据类型手册，如何将“ORB2.0000000001”转换为整数？
