How Can I Convert a String to a Type in C#?

String type conversion in C#

In C# programming, it is often necessary to dynamically convert a string representing a class name into its corresponding type. However, using Type.GetType("System.Int32") this default method only works for types located in mscorlib or in the calling assembly.

For classes located in other assemblies, a different approach is required. The required type can be successfully retrieved by including the assembly name in the string:

<code class="language-csharp">Type type = Type.GetType("命名空间.我的类, 我的程序集");</code>

If the assembly has a strong name, its details must be included. For more guidance, please refer to the Type.GetType(string) documentation.

Alternatively, assume you hold a reference to the target assembly, e.g. via a known type. In this case, Assembly.GetType provides a convenient solution:

<code class="language-csharp">Assembly asm = typeof(某个已知类型).Assembly;
Type type = asm.GetType(带命名空间的类型名称);</code>

Using the above techniques, you can easily implement string to type conversion in C#, thereby fully realizing the potential of dynamic type retrieval.
