Mixing
Building a new variable from a byte list
I am trying to write a data logger GUI. This application receives information over serial port about the variables that are defined in an embedded software.
I have a class for storing these variables. A new instance of this class is created everytime a new variable is requested in watch-window.
public class Var_t
{
public string vType; //variable type chosen from a combobox
public string vName; //variable name read from the serial port
public UInt32 vAddr; //variable ram addr read from the serial port
public byte vSize; //variable size read from the serial port
public List<byte> vBuffer; //variable content buffer
};
Since the variable size and type are read dynamically at the runtime, I'm just filling the byte List while receiving the value of this variable.
I need a class that combines these bytes using the vType datatype after the transfer is completed. This class will return a string to let me show the variable value in a combo-box to the user:
public class BuildVariable(List<byte> varBuf, string varType)
{
string ValueStr;
//I tried using BitConverter to combine the bytes into a new object
//but it does not accept any parameter for the type
return ValueStr;
};
Possible variable types are byte, uint8, int8, uint16, int16, uint32, int32, uint64, int64, float, double,char,string

Simplest way is to simply switch on vType or use a dictionary with vType as key & a BitConverter lambda as value.

I'm not very experienced in C# actually. I know how and why we use the dictionary but I don't know much about lambda. Would you please give me an example or a reference about what you mean? Do you think I should add an example to my question?

This is what I ended up with:
public static string GetTypedString(Var_t varToDisp)
{
string ValueDisplay;
switch (varToDisp.vType)
{
case "byte":
lock (varToDisp.value)
{
byte temp_byte = varToDisp.vBuffer[0];
ValueDisplay = temp_byte.ToString();
}
break;
case "uint16":
lock (varToDisp.value)
{
UInt16 temp_ui16 = BitConverter.ToUInt16(varToDisp.vBuffer.ToArray<byte>(), 0);
ValueDisplay = temp_ui16.ToString();
}
break;
case "uint32":
lock (varToDisp.value)
{
UInt32 temp_uint32 = BitConverter.ToUInt32(varToDisp.vBuffer.ToArray<byte>(), 0);
ValueDisplay = temp_uint32.ToString();
}
break;
//and so on..
}
return ValueDisplay;
}
I couldn't find a way to do it with a dynamic type selection, so I had to do the conversion one by one.
