本文介绍了一个C#应用程序如何加载并解析DLL文件中的类型、方法及属性。通过按钮点击事件触发，程序读取指定DLL文件，列出所有公共类型、方法数量及名称，并进一步获取非公开属性的数量。

///
///
/// loads a *.dll file from txtMethods and invokes all methods int it.
/// lists all types in the assembly

private void btnList_Click(object sender, System.EventArgs e)
{

string fileName=labelFile.Text.Trim();
string result="";
txtMethods.Text="";
txtTypes.Text="";

if(File.Exists(fileName))
{
try
{
Assembly assembly=Assembly.LoadFrom(fileName);
Type[] types=assembly.GetTypes();
result="The Assembly contains the following types :"+Environment.NewLine;

for(int i=0;i {
result+=" "+i+":"+types[i].Name+" "+" "+Environment.NewLine;

// Get the public methods.
MethodInfo[] myArrayMethodInfo=types[i].GetMethods(BindingFlags.Public|BindingFlags.Instance|BindingFlags.DeclaredOnly); txtMethods.Text=txtMethods.Text+Environment.NewLine+"The number of public methods in "+types[i].Name+" is "+myArrayMethodInfo.Length+Environment.NewLine;
// get all the methods.
txtMethods.Text=txtMethods.Text+getMethodInfo(myArrayMethodInfo);
/*

Console.WriteLine(" The number of protected methods is {0}.", myArrayMethodInfo1.Length);
// Display information for all methods.

}

foreach(Type myType in types)
{
// Get the public properties.
PropertyInfo[] myPropertyInfo = myType.GetProperties(BindingFlags.Public|BindingFlags.Instance);
