如何在 Web 参考中处理 CLS 兼容问题？
我正在 C# 解决方案的程序集中打开 [程序集：System.CLSCompliant(true)]。
我现在在为 SharePoint Web 服务生成的代码中收到一些警告。
以下是不符合 CLS 的方法之一：
/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://schemas.microsoft.com/sharepoint/soap/GetItem", RequestNamespace="http://schemas.microsoft.com/sharepoint/soap/", ResponseNamespace="http://schemas.microsoft.com/sharepoint/soap/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public uint GetItem(string Url, out FieldInformation[] Fields, [System.Xml.Serialization.XmlElementAttribute(DataType="base64Binary")] out byte[] Stream) {
object[] results = this.Invoke("GetItem", new object[] {
Url});
Fields = ((FieldInformation[])(results[1]));
Stream = ((byte[])(results[2]));
return ((uint)(results[0]));
}
如何删除此警告？
谢谢你， 基思
I am turning on [assembly: System.CLSCompliant(true)] inside the assemblies of my C# solution.
I am now getting a few warnings inside the generated code for a SharePoint Web Service.
Here is one of the methods that are not CLS-compliant:
/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://schemas.microsoft.com/sharepoint/soap/GetItem", RequestNamespace="http://schemas.microsoft.com/sharepoint/soap/", ResponseNamespace="http://schemas.microsoft.com/sharepoint/soap/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public uint GetItem(string Url, out FieldInformation[] Fields, [System.Xml.Serialization.XmlElementAttribute(DataType="base64Binary")] out byte[] Stream) {
object[] results = this.Invoke("GetItem", new object[] {
Url});
Fields = ((FieldInformation[])(results[1]));
Stream = ((byte[])(results[2]));
return ((uint)(results[0]));
}
How can I remove this warning?
Thank you,
Keith

您可以使用
[CLSCompliant(false)]属性标记不兼容的方法以避免警告，但这似乎首先破坏了将程序集标记为兼容的目标：大概您想要代码实际上符合 CLS。为了使代码符合要求，您需要从 < 更改方法的返回类型代码>uint/
UInt32。 公开的无符号类型不符合 CLS。您可以返回
long/Int64代替。long类型符合 CLS，并将安全地处理任何可能的uint值。如果您不能或不会编辑生成的代码（以添加属性或更改返回类型），那么我认为您唯一的选择就是将该代码移动到单独的、不兼容的程序集 正如约翰建议的。
You can mark the non-compliant methods with the
[CLSCompliant(false)]attribute to avoid the warnings, but that seems to defeat the object of marking your assemblies as compliant in the first place: Presumably you want the code to actually be CLS-compliant.To make the code comply, you need to change the return type of the method from
uint/UInt32. Exposed unsigned types aren't CLS-compliant.You could return
long/Int64instead. Thelongtype is CLS-compliant and will safely handle any possibleuintvalue.If you can't, or won't, edit the generated code (to either add the attribute or alter the return type) then I think your only option is to move that code to a separate, non-compliant assembly as John suggests.
我建议您将 Web 引用放置在未设置为符合 CLS 的单独的类库项目中。 从主代码中引用该库。
I'd recommend you place your web references in a separate class library project that is not set to be CLS-compliant. Reference that library from your main code.
