验证C#字符串是否为有效的XML Schema anyURI

public bool VerifyAnyURI(string anyUriValue)
{ 
    bool result = false;
    try
    {
        SoapAnyUri anyUri = new SoapAnyUri(anyUriValue);
        result = true;
    }
    catch (Exception)
    {
    }
    return result;
}

此构造函数似乎不会抛出任何类型的异常.从技术上讲,任何有效字符串都是有效的anyURI吗？

anyURI数据类型is defined as follows：

[Definition:] anyURI represents a Uniform Resource Identifier Reference (URI). An anyURI value can be absolute or relative, and may have an optional fragment identifier (i.e., it may be a URI Reference). This type should be used to specify the intention that the value fulfills the role of a URI as defined by [RFC 2396], as amended by [RFC 2732].

因此,您只需使用Uri.TryCreate和UriKind.RelativeOrAbsolute来验证字符串是否代表有效值：

Uri uri;
bool valid = Uri.TryCreate(anyUriValue, UriKind.RelativeOrAbsolute, out uri);
