1. Use

Easy to use:

 

Enter the path of the TXT text file to be converted, and then save the EXE path. Configure the text, color, program title, and other options ......

Finally, save the file and an EXE file is generated.

 

Double-click it to open it:

 

A configuration-based exe will display the TXT content. Haha.

The program is written in WPF. Of course, the EXE file generated by txt is also a WPF program. The program logic is very simple, that is, the Reflection emit is used to automatically generate a WPF program.

 

Reflection emit:

• . Net (C #): Reflection emit to generate WPF Program
• More of these articles: http://www.cnblogs.com/mgen/tag/Emit/

Interface:

• WPF pure XAML supports system font and color selection for previewing ComboBox

 

However, there are still some things to note: When writing colors, because the colors are dynamic (depending on user input), a local variable is first stored in ilgenerator to store a brushconverter in WPF. Then call brushconverter. convertfromstring to obtain the dynamic color (the brush type in WPF) when reflecting the emit generation code ). Finally, use the castclass command in Il to convert the object returned by the typeconverter. convertfromstring Method to the desired brush object.

// + Using system. reflection;

// + Using system. reflection. emit;

// Return the solidcolorbrush with the specified name in the current execution stack

// Conv stores a brushconverter variable in ilgenerator.

Static void genbrush (ilgenerator ilgen, string name, localbuilder Conv)

{

Ilgen. emit (Opcodes. ldloc, Conv );

Ilgen. emit (Opcodes. ldstr, name );

// Call brushconverter. convertfromstring

Ilgen. emit (Opcodes. callvirt,

Typeof (brushconverter). getmethod ("convertfromstring", new type [] {typeof (string )}));

// Convert the object type to the brush type

Ilgen. emit (Opcodes. castclass, typeof (Brush ));

 

}

 

The second is that the main functions of UI programs such as WPF need the stathreadattribute feature. In this case, the setcustomattribute method of customattributebuilder and assemblybuilder must be used to add custom features when emit is generated.

Code:

// + Using system. reflection;

// + Using system. reflection. emit;

 

// Create assemblybuilder, modulebuilder, typebuilder, and methodbuilder.

VaR assbuilder = appdomain. currentdomain. definedynamicassembly (

New assemblyname (assname ),

Assemblybuilderaccess. runandsave );

VaR modbuilder = assbuilder. definedynamicmodule (assname, filename );

VaR typebuilder = modbuilder. definetype ("program ");

VaR methodbuilder = typebuilder. definemethod (

"Main ",

Methodattributes. Static | methodattributes. hidebysig,

Callingconventions. Standard,

Null,

New Type [0]);

 

// Set stathreadattribute

VaR customattrbuilder = new customattributebuilder (

Typeof (stathreadattritor). getconstructor (New Type [0]), new object [0]);

Methodbuilder. setcustomattribute (customattrbuilder );
