怎么解决这个错误 ？"An object reference is required for the nonstatic field"
下面是 Vendor.cs文件的内容
开始在开始处声明
private AcmeReaderLayer reader1;
// AcmeReaderLayer 是一个类文件
函数里的一段代码：
byte[] aa = new byte[36];
ApplyPropertyProfileCommand applyPropertyProfileCommand = (ApplyPropertyProfileCommand)command;
if (null != applyPropertyProfileCommand.PropertyProfile)
{
foreach (KeyValuePair <PropertyKey, object> property in applyPropertyProfileCommand.PropertyProfile)
{
bool error = false;
try
{
aa=setAppProperty((AcmeReaderLayer)reader1, (string)property.Key.PropertyName, (string)property.Value);
在这错误： “ Error3An object reference is required for the nonstatic field, method,orproperty Microsoft.Rfid.Reader.Driver.Acme.VendorHelper.setAppProperty(Microsoft.Rfid.Reader.Driver.Acme.Framework.AcmeReaderLayer, string, string) '“
}
catch (Exception e)
{
throw new ConnectionFailedException( "SetProperty to reader failed ", e, " ", null);
}
}
setAppProperty函数声明如下：
internal byte[] setAppProperty(AcmeReaderLayer reader1, string propertyName, string propertyValue)
{
this.reader1 = reader1;
byte[] para = { 0x01, 0x02 };
switch (propertyName)
{
case "ID ":
return para;
break;
case "NAME ":
reader.name = propertyValue; //TODO: Currently unsupported.
return para;
break;
}
}
[解决办法]
是不是因为你的reader1没有初始化...

函数里的一段代码：
aa=setAppProperty((AcmeReaderLayer)reader1, (string)property.Key.PropertyName, (string)property.Value);
在这错误： “ Error3An object reference is required for the nonstatic field, method,orproperty Microsoft.Rfid.Reader.Driver.Acme.VendorHelper.setAppProperty(Microsoft.Rfid.Reader.Driver.Acme.Framework.AcmeReaderLayer, string, string) '“
=================
这段函数代码在什么样的一个函数里
An object reference is required for the nonstatic field
你这段函数是static的？？？
