代码出错

[cxxlp]

	
		VARIANT variant_inp;
		  COleSafeArray safearray_inp;
		LONG len,k;
		 BYTE rxdata[2048];
		 CString strtemp;



	if(m_ctrlComm.GetCommEvent() == 2){

		
		variant_inp=m_ctrlComm.GetInput(); //读缓冲区
		safearray_inp=variant_inp; //VARIANT型变量转换为ColeSafeArray型变量
		len="safearray"_inp.GetOneDimSize(); //得到有效数据长度     //error C2146: syntax error : missing ';' before identifier '_inp'   怎么换啊????
