c++ - 错误 C2678 : '==' binary: no operator found which takes a left operand of type 'CSchemaString' (or there is no acceptable conversion)

Question

我正在将项目从 VC++6 转移到 VC++2005，在编译时出现以下错误。

error C2678: '==' binary: no operator found which takes a left operand of type 'CSchemaString' (or there is no acceptable conversion)

这是代码；

CSchemaString References("id");
for(j=0;j<=tpChild.GetUpperBound();j++)
{
    if(References == "id") //error C2678: '==' binary: no operator found which takes a left operand of type 'CSchemaString' (or there is no acceptable conversion)

        References = References + intToString(((Component*)tpChild.GetAt(j))->GetComponentID()) +"_"+ ((Component*)tpChild.GetAt(j))->GetName();
    else
        References = References + " id" + intToString(((Component*)tpChild.GetAt(j))->GetComponentID()) +"_"+((Component*)tpChild.GetAt(j))->GetName();
}
if(References != "id") //si references n'est pas vide
    XComponent.AddPlant_Item_Ref(References);



return XComponent;

感谢任何帮助。

CSchemaString 不是字符串。你需要做的

References.ToString() == "id"
